f5dcb68086 ARM: SoC: driver updates for v4.2
Some of these are for drivers/soc, where we're now putting
 SoC-specific drivers these days. Some are for other driver subsystems
 where we have received acks from the appropriate maintainers.
 
 Some highlights:
 
 - simple-mfd: document DT bindings and misc updates
 - migrate mach-berlin to simple-mfd for clock, pinctrl and reset
 - memory: support for Tegra132 SoC
 - memory: introduce tegra EMC driver for scaling memory frequency
 - misc. updates for ARM CCI and CCN busses
 
  Conflicts:
 	arch/arm64/boot/dts/arm/juno-motherboard.dtsi
 
  Trivial add/add conflict with our dt branch.
  Resolution: take both sides.

5212e11fde nd_btt: atomic sector updates
BTT stands for Block Translation Table, and is a way to provide power
fail sector atomicity semantics for block devices that have the ability
to perform byte granularity IO. It relies on the capability of libnvdimm
namespace devices to do byte aligned IO.

The BTT works as a stacked blocked device, and reserves a chunk of space
from the backing device for its accounting metadata. It is a bio-based
driver because all IO is done synchronously, and there is no queuing or
asynchronous completions at either the device or the driver level.

The BTT uses 'lanes' to index into various 'on-disk' data structures,
and lanes also act as a synchronization mechanism in case there are more
CPUs than available lanes. We did a comparison between two lane lock
strategies - first where we kept an atomic counter around that tracked
which was the last lane that was used, and 'our' lane was determined by
atomically incrementing that. That way, for the nr_cpus > nr_lanes case,
theoretically, no CPU would be blocked waiting for a lane. The other
strategy was to use the cpu number we're scheduled on to and hash it to
a lane number. Theoretically, this could block an IO that could've
otherwise run using a different, free lane. But some fio workloads
showed that the direct cpu -> lane hash performed faster than tracking
'last lane' - my reasoning is the cache thrash caused by moving the
atomic variable made that approach slower than simply waiting out the
in-progress IO. This supports the conclusion that the driver can be a
very simple bio-based one that does synchronous IOs instead of queuing.

5202efe544 coredump: use from_kuid/kgid when formatting corename
When adding __printf attribute to cn_printf, gcc reports some issues:

  fs/coredump.c:213:5: warning: format '%d' expects argument of type
  'int', but argument 3 has type 'kuid_t' [-Wformat=]
       err = cn_printf(cn, "%d", cred->uid);
       ^
  fs/coredump.c:217:5: warning: format '%d' expects argument of type
  'int', but argument 3 has type 'kgid_t' [-Wformat=]
       err = cn_printf(cn, "%d", cred->gid);
       ^

These warnings come from the fact that the value of uid/gid needs to be
extracted from the kuid_t/kgid_t structure before being used as an
integer.  More precisely, cred->uid and cred->gid need to be converted to
either user-namespace uid/gid or to init_user_ns uid/gid.

Use init_user_ns in order not to break existing ABI, and document this in
Documentation/sysctl/kernel.txt.

While at it, format uid and gid values with %u instead of %d because
uid_t/__kernel_uid32_t and gid_t/__kernel_gid32_t are unsigned int.

e2f15f9a79 netconsole: implement extended console support
printk logbuf keeps various metadata and optional key=value dictionary for
structured messages, both of which are stripped when messages are handed
to regular console drivers.

It can be useful to have this metadata and dictionary available to
netconsole consumers.  This obviously makes logging via netconsole more
complete and the sequence number in particular is useful in environments
where messages may be lost or reordered in transit - e.g.  when netconsole
is used to collect messages in a large cluster where packets may have to
travel congested hops to reach the aggregator.  The lost and reordered
messages can easily be identified and handled accordingly using the
sequence numbers.

printk recently added extended console support which can be selected by
setting CON_EXTENDED flag.  From console driver side, not much changes.
The only difference is that the text passed to the write callback is
formatted the same way as /dev/kmsg.

This patch implements extended console support for netconsole which can be
enabled by either prepending "+" to a netconsole boot param entry or
echoing 1 to "extended" file in configfs.  When enabled, netconsole
transmits extended log messages with headers identical to /dev/kmsg
output.

There's one complication due to message fragments.  netconsole limits the
maximum message size to 1k and messages longer than that are split into
multiple fragments.  As all extended console messages should carry
matching headers and be uniquely identifiable, each extended message
fragment carries full copy of the metadata and an extra header field to
identify the specific fragment.  The optional header is of the form
"ncfrag=OFF/LEN" where OFF is the byte offset into the message body and
LEN is the total length.

To avoid unnecessarily making printk format extended messages, Extended
netconsole is registered with printk when the first extended netconsole is
configured.

6fe29354be printk: implement support for extended console drivers
printk log_buf keeps various metadata for each message including its
sequence number and timestamp.  The metadata is currently available only
through /dev/kmsg and stripped out before passed onto console drivers.  We
want this metadata to be available to console drivers too so that console
consumers can get full information including the metadata and dictionary,
which among other things can be used to detect whether messages got lost
in transit.

This patch implements support for extended console drivers.  Consoles can
indicate that they want extended messages by setting the new CON_EXTENDED
flag and they'll be fed messages formatted the same way as /dev/kmsg.

 "<level>,<sequnum>,<timestamp>,<contflag>;<message text>\n"

If extended consoles exist, in-kernel fragment assembly is disabled.  This
ensures that all messages emitted to consoles have full metadata including
sequence number.  The contflag carries enough information to reassemble
the fragments from the reader side trivially.  Note that this only affects
/dev/kmsg.  Regular console and /proc/kmsg outputs are not affected by
this change.

* Extended message formatting for console drivers is enabled iff there
  are registered extended consoles.

* Comment describing /dev/kmsg message format updated to add missing
  contflag field and help distinguishing variable from verbatim terms.

c00ed16a9e zswap: runtime enable/disable
Change the "enabled" parameter to be configurable at runtime.  Remove the
enabled check from init(), and move it to the frontswap store() function;
when enabled, pages will be stored, and when disabled, pages won't be
stored.

This is almost identical to Seth's patch from 2 years ago:

6566d1a32b zram: add dynamic device add/remove functionality
We currently don't support on-demand device creation.  The one and only
way to have N zram devices is to specify num_devices module parameter
(default value: 1).  IOW if, for some reason, at some point, user wants
to have N + 1 devies he/she must umount all the existing devices, unload
the module, load the module passing num_devices equals to N + 1.  And do
this again, if needed.

This patch introduces zram control sysfs class, which has two sysfs
attrs:
- hot_add      -- add a new zram device
- hot_remove   -- remove a specific (device_id) zram device

hot_add sysfs attr is read-only and has only automatic device id
assignment mode (as requested by Minchan Kim).  read operation performed
on this attr creates a new zram device and returns back its device_id or
error status.

Usage example:
	# add a new specific zram device
	cat /sys/class/zram-control/hot_add
	2

	# remove a specific zram device
	echo 4 > /sys/class/zram-control/hot_remove

Returning zram_add() error code back to user (-ENOMEM in this case)

	cat /sys/class/zram-control/hot_add
	cat: /sys/class/zram-control/hot_add: Cannot allocate memory

NOTE, there might be users who already depend on the fact that at least
zram0 device gets always created by zram_init(). Preserve this behavior.

c3cdb40e66 zram: remove max_num_devices limitation
Limiting the number of zram devices to 32 (default max_num_devices value)
is confusing, let's drop it.  A user with 2TB or 4TB of RAM, for example,
can request as many devices as he can handle.

3d8ed88ba7 zram: add compact sysfs entry to documentation
We currently don't support zram on-demand device creation.  The only way
to have N zram devices is to specify num_devices module parameter (default
value 1).  That means that if, for some reason, at some point, user wants
to have N + 1 devies he/she must umount all the existing devices, unload
the module, load the module passing num_devices equals to N + 1.

This patchset introduces zram-control sysfs class, which has two sysfs

        1

        # remove a specific zram device

863ef5ba29 Documentation: ABI: sysfs-firmware-dmi: add -entries suffix to file name
The dmi-sysfs module adds DMI table structures entries under
/sys/firmware/dmi/entries only, so rename documentation file to
sysfs-firmware-dmi-entries as more appropriate. Without renaming it's
confusing to differ this from sysfs-firmware-dmi-tables that adds raw
DMI table and actually adds "dmi" kobject.

d7f96f97c4 firmware: dmi_scan: add SBMIOS entry and DMI tables
Some utils, like dmidecode and smbios, need to access SMBIOS entry
table area in order to get information like SMBIOS version, size, etc.
Currently it's done via /dev/mem. But for situation when /dev/mem
usage is disabled, the utils have to use dmi sysfs instead, which
doesn't represent SMBIOS entry and adds code/delay redundancy when direct
access for table is needed.

So this patch creates dmi/tables and adds SMBIOS entry point to allow
utils in question to work correctly without /dev/mem. Also patch adds
raw dmi table to simplify dmi table processing in user space, as
proposed by Jean Delvare.

 other core platform code. Some highlights from this round:
 
 - sunxi: SMP support for A23 SoC
 - socpga: big-endian support
 - pxa: conversion to common clock framework
 - bcm: SMP support for BCM63138
 - imx: support new I.MX7D SoC
 - zte: basic support for ZX296702 SoC
 
  Conflicts:
 	arch/arm/mach-socfpga/core.h
 
 Trivial remove/remove conflict with our cleanup branch.
 Resolution: remove both sides

9b012a29a3 Documentation/vm/unevictable-lru.txt: clarify MAP_LOCKED behavior
There is a very subtle difference between mmap()+mlock() vs
mmap(MAP_LOCKED) semantic.  The former one fails if the population of the
area fails while the later one doesn't.  This basically means that
mmap(MAPLOCKED) areas might see major fault after mmap syscall returns
which is not the case for mlock.  mmap man page has already been altered
but Documentation/vm/unevictable-lru.txt deserves a clarification as well.

fe4ba3c343 watchdog: add watchdog_cpumask sysctl to assist nohz
Change the default behavior of watchdog so it only runs on the
housekeeping cores when nohz_full is enabled at build and boot time.
Allow modifying the set of cores the watchdog is currently running on
with a new kernel.watchdog_cpumask sysctl.

In the current system, the watchdog subsystem runs a periodic timer that
schedules the watchdog kthread to run.  However, nohz_full cores are
designed to allow userspace application code running on those cores to
have 100% access to the CPU.  So the watchdog system prevents the
nohz_full application code from being able to run the way it wants to,
thus the motivation to suppress the watchdog on nohz_full cores, which
this patchset provides by default.

However, if we disable the watchdog globally, then the housekeeping
cores can't benefit from the watchdog functionality.  So we allow
disabling it only on some cores.  See Documentation/lockup-watchdogs.txt
for more information.

e3d8238d7f arm64 updates for 4.2, mostly refactoring/clean-up:
- CPU ops and PSCI (Power State Coordination Interface) refactoring
   following the merging of the arm64 ACPI support, together with
   handling of Trusted (secure) OS instances
 
 - Using fixmap for permanent FDT mapping, removing the initial dtb
   placement requirements (within 512MB from the start of the kernel
   image). This required moving the FDT self reservation out of the
   memreserve processing
 
 - Idmap (1:1 mapping used for MMU on/off) handling clean-up
 
 - Removing flush_cache_all() - not safe on ARM unless the MMU is off.
   Last stages of CPU power down/up are handled by firmware already
 
 - "Alternatives" (run-time code patching) refactoring and support for
   immediate branch patching, GICv3 CPU interface access
 
 - User faults handling clean-up
 
 And some fixes:
 
 - Fix for VDSO building with broken ELF toolchains
 
 - Fixing another case of init_mm.pgd usage for user mappings (during
   ASID roll-over broadcasting)
 
 - Fix for FPSIMD reloading after CPU hotplug

6eae81a5e2 IOMMU Updates for Linux v4.2
This time with bigger changes than usual:
 
 	* A new IOMMU driver for the ARM SMMUv3. This IOMMU is pretty
 	  different from SMMUv1 and v2 in that it is configured through
 	  in-memory structures and not through the MMIO register region.
 	  The ARM SMMUv3 also supports IO demand paging for PCI devices
 	  with PRI/PASID capabilities, but this is not implemented in
 	  the driver yet.
 
 	* Lots of cleanups and device-tree support for the Exynos IOMMU
 	  driver. This is part of the effort to bring Exynos DRM support
 	  upstream.
 
 	* Introduction of default domains into the IOMMU core code. The
 	  rationale behind this is to move functionalily out of the
 	  IOMMU drivers to common code to get to a unified behavior
 	  between different drivers.
 	  The patches here introduce a default domain for iommu-groups
 	  (isolation groups). A device will now always be attached to a
 	  domain, either the default domain or another domain handled by
 	  the device driver. The IOMMU drivers have to be modified to
 	  make use of that feature. So long the AMD IOMMU driver is
 	  converted, with others to follow.
 
 	* Patches for the Intel VT-d drvier to fix DMAR faults that
 	  happen when a kdump kernel boots. When the kdump kernel boots
 	  it re-initializes the IOMMU hardware, which destroys all
 	  mappings from the crashed kernel. As this happens before

Pull IOMMU updates from Joerg Roedel:
 "This time with bigger changes than usual:

   - A new IOMMU driver for the ARM SMMUv3.

     This IOMMU is pretty different from SMMUv1 and v2 in that it is
     configured through in-memory structures and not through the MMIO
     register region.  The ARM SMMUv3 also supports IO demand paging for
     PCI devices with PRI/PASID capabilities, but this is not
     implemented in the driver yet.

   - Lots of cleanups and device-tree support for the Exynos IOMMU
     driver.  This is part of the effort to bring Exynos DRM support
     upstream.

   - Introduction of default domains into the IOMMU core code.

     The rationale behind this is to move functionalily out of the IOMMU
     drivers to common code to get to a unified behavior between
     different drivers.  The patches here introduce a default domain for
     iommu-groups (isolation groups).

     A device will now always be attached to a domain, either the
     default domain or another domain handled by the device driver.  The
     IOMMU drivers have to be modified to make use of that feature.  So
     long the AMD IOMMU driver is converted, with others to follow.

   - Patches for the Intel VT-d drvier to fix DMAR faults that happen
     when a kdump kernel boots.

     When the kdump kernel boots it re-initializes the IOMMU hardware,
     which destroys all mappings from the crashed kernel.  As this
     happens before the endpoint devices are re-initialized, any
     in-flight DMA causes a DMAR fault.  These faults cause PCI master
     aborts, which some devices can't handle properly and go into an
     undefined state, so that the device driver in the kdump kernel
     fails to initialize them and the dump fails.

     This is now fixed by copying over the mapping structures (only
     context tables and interrupt remapping tables) from the old kernel
     and keep the old mappings in place until the device driver of the
     new kernel takes over.  This emulates the the behavior without an
     IOMMU to the best degree possible.

   - A couple of other small fixes and cleanups"

7fe0bf908d regulator: Updates for v4.2
Another fairly quiet release, some new drivers with generic handling for
 minor features but nothing that makes a substantial difference outside
 of the subsystem or for most boards:
 
  - Support for a bunch of new parameters which are present on enough
    regulators to be worth having generic handling for in the framework.
  - Fixes for some issues with printing constraints during boot which
    should probably have gone in for v4.1 but didn't.
  - New drivers for Dialog DA9062, Maxim MAX77621 and Qualcomm SPMI regulators.

 There are also one new driver: the Cisco snic; the advansys driver has
 been rewritten to get rid of the warning about converting it to the
 DMA API, the tape statistics patch got in and finally, there's a
 resuffle of SCSI header files to separate more cleanly initiator from

Merge tag 'pm+acpi-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management and ACPI updates from Rafael Wysocki:
 "The rework of backlight interface selection API from Hans de Goede
  stands out from the number of commits and the number of affected
  places perspective.  The cpufreq core fixes from Viresh Kumar are
  quite significant too as far as the number of commits goes and because
  they should reduce CPU online/offline overhead quite a bit in the
  majority of cases.

  From the new featues point of view, the ACPICA update (to upstream
  revision 20150515) adding support for new ACPI 6 material to ACPICA is
  the one that matters the most as some new significant features will be
  based on it going forward.  Also included is an update of the ACPI
  device power management core to follow ACPI 6 (which in turn reflects
  the Windows' device PM implementation), a PM core extension to support
  wakeup interrupts in a more generic way and support for the ACPI _CCA
  device configuration object.

  The rest is mostly fixes and cleanups all over and some documentation
  updates, including new DT bindings for Operating Performance Points.

  There is one fix for a regression introduced in the 4.1 cycle, but it
  adds quite a number of lines of code, it wasn't really ready before
  Thursday and you were on vacation, so I refrained from pushing it on
  the last minute for 4.1.

  Specifics:

   - ACPICA update to upstream revision 20150515 including basic support

10b4b096d0 This is the big bulk of GPIO changes queued for the v4.2
kernel series:
 
 - A big set of cleanups to the aged sysfs interface from
   Johan Hovold. To get these in, v4.1-rc3 was merged into
   the tree as the first patch in that series had to go
   into stable. This makes the locking much more fine-grained
   (get rid of the "big GPIO lock(s)" and store states in the
   GPIO descriptors.
 
 - Rename gpiod_[g|s]et_array() to gpiod_[g|s]et_array_value()
   to avoid confusions.
 
 - New drivers for:
   - NXP LPC18xx (currently LPC1850)
   - NetLogic XLP
   - Broadcom STB SoC's
   - Axis ETRAXFS
   - Zynq Ultrascale+ (subdriver)
 
 - ACPI:
   - Make it possible to retrieve GpioInt resources from
     a GPIO device using acpi_dev_gpio_irq_get()
   - Merge some dependent I2C changes exploiting this.
   - Support the ARM X-Gene GPIO standby driver.
 
 - Make it possible for the generic GPIO driver to read
   back the value set registers to reflect current
   status.
 
 - Loads of OMAP IRQ handling fixes.
 
 - Incremental improvements to Kona, max732x, OMAP, MXC, RCAR,
   PCA953x, STP-XWAY, PCF857x, Crystalcove, TB10x.
 
 - Janitorial (contification, checkpatch cleanups)

Pull x86 core updates from Ingo Molnar:
 "There were so many changes in the x86/asm, x86/apic and x86/mm topics
  in this cycle that the topical separation of -tip broke down somewhat -
  so the result is a more traditional architecture pull request,
  collected into the 'x86/core' topic.

  The topics were still maintained separately as far as possible, so
  bisectability and conceptual separation should still be pretty good -
  but there were a handful of merge points to avoid excessive
  dependencies (and conflicts) that would have been poorly tested in the
  end.

  The next cycle will hopefully be much more quiet (or at least will
  have fewer dependencies).

  The main changes in this cycle were:

   * x86/apic changes, with related IRQ core changes: (Jiang Liu, Thomas
     Gleixner)

     - This is the second and most intrusive part of changes to the x86
       interrupt handling - full conversion to hierarchical interrupt
       domains:

          [IOAPIC domain]   -----
                                 |
          [MSI domain]      --------[Remapping domain] ----- [ Vector domain ]
                                 |   (optional)          |
          [HPET MSI domain] -----                        |
                                                         |
          [DMAR domain]     -----------------------------
                                                         |
          [Legacy domain]   -----------------------------

       This now reflects the actual hardware and allowed us to distangle
       the domain specific code from the underlying parent domain, which
       can be optional in the case of interrupt remapping.  It's a clear
       separation of functionality and removes quite some duct tape
       constructs which plugged the remap code between ioapic/msi/hpet
       and the vector management.

     - Intel IOMMU IRQ remapping enhancements, to allow direct interrupt
       injection into guests (Feng Wu)

   * x86/asm changes:

     - Tons of cleanups and small speedups, micro-optimizations.  This
       is in preparation to move a good chunk of the low level entry
       code from assembly to C code (Denys Vlasenko, Andy Lutomirski,
       Brian Gerst)

     - Moved all system entry related code to a new home under
       arch/x86/entry/ (Ingo Molnar)

     - Removal of the fragile and ugly CFI dwarf debuginfo annotations.
       Conversion to C will reintroduce many of them - but meanwhile
       they are only getting in the way, and the upstream kernel does
       not rely on them (Ingo Molnar)

     - NOP handling refinements. (Borislav Petkov)

   * x86/mm changes:

     - Big PAT and MTRR rework: making the code more robust and
       preparing to phase out exposing direct MTRR interfaces to drivers -
       in favor of using PAT driven interfaces (Toshi Kani, Luis R
       Rodriguez, Borislav Petkov)

     - New ioremap_wt()/set_memory_wt() interfaces to support
       Write-Through cached memory mappings.  This is especially
       important for good performance on NVDIMM hardware (Toshi Kani)

   * x86/ras changes:

     - Add support for deferred errors on AMD (Aravind Gopalakrishnan)

       This is an important RAS feature which adds hardware support for
       poisoned data.  That means roughly that the hardware marks data
       which it has detected as corrupted but wasn't able to correct, as
       poisoned data and raises an APIC interrupt to signal that in the
       form of a deferred error.  It is the OS's responsibility then to
       take proper recovery action and thus prolonge system lifetime as
       far as possible.

     - Add support for Intel "Local MCE"s: upcoming CPUs will support
       CPU-local MCE interrupts, as opposed to the traditional system-
       wide broadcasted MCE interrupts (Ashok Raj)

     - Misc cleanups (Borislav Petkov)

   * x86/platform changes:

     - Intel Atom SoC updates

  ... and lots of other cleanups, fixlets and other changes - see the
  shortlog and the Git log for details"

Pull x86 FPU updates from Ingo Molnar:
 "This tree contains two main changes:

   - The big FPU code rewrite: wide reaching cleanups and reorganization
     that pulls all the FPU code together into a clean base in
     arch/x86/fpu/.

     The resulting code is leaner and faster, and much easier to
     understand.  This enables future work to further simplify the FPU
     code (such as removing lazy FPU restores).

     By its nature these changes have a substantial regression risk: FPU
     code related bugs are long lived, because races are often subtle
     and bugs mask as user-space failures that are difficult to track
     back to kernel side backs.  I'm aware of no unfixed (or even
     suspected) FPU related regression so far.

   - MPX support rework/fixes.  As this is still not a released CPU
     feature, there were some buglets in the code - should be much more

Summary:
. Add atomic feature support
  - Exynos also now supports atomic feature. However, it doesn't
    guarantee atomic operation yet, and is required for more cleanups.
    This time we just modified for Exynos drm driver to use atomic
    interfaces instead of legacy ones. Next time, we will enhance
    Exynos drm driver to support the atomic operation.
. Add iommu support
  - This is a patch series according to below Exynos iommu integration
    work with DT and dma-mapping subsystem,
    http://lwn.net/Articles/607626/
. Consolidate Exynos drm driver initialization.
  - This patch sereis resolves the issue that only the first compoments
    was bound when happened deferred probing for other pipelines and
    also makes the driver to be more cleanned up by moving the dispered
    codes for registering kms drivers to one place.
. Add new MIC, DECON drivers, and MIPI-DSI support for Exynos5433.
  - Add MIC(Mobile image compressor) driver. MIC is a new IP for Exynos5433
    and later, which is used to transfer frame data to MIPI-DSI controller
    compressing the data to reduce memory bandwidth.
  - Add DECON driver for Exynos5433 SoC. This IP is a dislay controller
    similar to Exynos7's one but this controller has much different registers
    from Exynos7's ones so this driver has been implemented separately.
    We will implement a helper modules for FIMD and two DECON controllers
    to remove duplicated codes later.
  - Add Exynos5433 SoC support to MIPI-DSI driver, and device tree
    relevant patches.

Since it is building /usr/sbin/mpssd and /usr/sbin/micctrl
for x86_64 and the original authors indicated[1] that:

   MIC card is expected to work with x86_64 host, not with ppc64.
   We have never compiled on ppc host..

so it probably makes sense to just skip building these userspace
programs when we are cross compiling.

a9a80e7e31 PM / OPP: Allow multiple OPP tables to be passed via DT
On some platforms (Like Qualcomm's SoCs), it is not decided until
runtime on what OPPs to use. The OPP tables can be fixed at compile
time, but which table to use is found out only after reading some efuses
(sort of an prom) and knowing characteristics of the SoC.

To support such platform we need to pass multiple OPP tables per device
and hardware should be able to choose one and only one table out of
those.

Update operating-points-v2 bindings to support that.

b901b51807 PM / OPP: Add new bindings to address shortcomings of existing bindings
Current OPP (Operating performance point) device tree bindings have been
insufficient due to the inflexible nature of the original bindings. Over
time, we have realized that Operating Performance Point definitions and
usage is varied depending on the SoC and a "single size (just frequency,
voltage) fits all" model which the original bindings attempted and
failed.

The proposed next generation of the bindings addresses by providing a
expandable binding for OPPs and introduces the following common
shortcomings seen with the original bindings:

- Getting clock/voltage/current rails sharing information between CPUs.
  Shared by all cores vs independent clock per core vs shared clock per
  cluster.

- Support for specifying current levels along with voltages.

- Support for multiple regulators.

- Support for turbo modes.

- Other per OPP settings: transition latencies, disabled status, etc.?

- Expandability of OPPs in future.

This patch introduces new bindings "operating-points-v2" to get these problems
solved. Refer to the bindings for more details.

We now have multiple versions of OPP binding and only one of them should
be used per device.

This patch renames pll_clk to sclk_clk. The clock referenced by pll_clk
is actually not the pll input clock for dsi. The pll input clock comes
from the board's oscillator directly. But for the backward

resides between decon and mipi dsim, and compresses frame data by 50%.
With dsi, not display port, to send frame data to the panel, the
bandwidth is not enough. That is why this compressor is introduced.

208a128f6b ASoC: Updates for v4.2
The big thing this release has been Liam's addition of topology support
 to the core.  We've also seen quite a bit of driver work and the
 continuation of Lars' refactoring for component support.
 
  - Support for loading ASoC topology maps from firmware, intended to be
    used to allow self-describing DSP firmware images to be built which
    can map controls added by the DSP to userspace without the kernel
    needing to know about individual DSP firmwares.
  - Lots of refactoring to avoid direct access to snd_soc_codec where
    it's not needed supporting future refactoring.
  - Big refactoring and cleanup serieses for the Wolfson ADSP and TI
    TAS2552 drivers.
  - Support for TI TAS571x power amplifiers.
  - Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
  - Support for x86 systems with RT5650 and Qualcomm Storm.
