83ededdb72 docs: Add initial documentation for devfreq
The devfreq subsystem has plenty of kernel-doc comments but they're not
currently included in sphinx documentation.

Add a minimal devfreq.rst file which mostly just includes kernel-doc
comments from devfreq source. This also exposes a number of kernel-doc
warnings on `make htmldocs`

95364f3670 ata: make qc_prep return ata_completion_errors
In case a driver wants to return an error from qc_prep, return enum
ata_completion_errors. sata_mv is one of those drivers -- see the next
patch. Other drivers return the newly defined AC_ERR_OK.

[v2] use enum ata_completion_errors and AC_ERR_OK.

e2ae9bcc4a driver core: Add support for linking devices during device addition
The firmware corresponding to a device (dev.fwnode) might be able to
provide functional dependency information between a device and its
supplier and consumer devices.  Tracking this functional dependency
allows optimizing device probe order and informing a supplier when all
its consumers have probed (and thereby actively managing their
resources).

The existing device links feature allows tracking and using
supplier-consumer relationships. So, this patch adds the add_links()
fwnode callback to allow firmware to create device links for each
device as the device is added.

However, when consumer devices are added, they might not have a supplier
device to link to despite needing mandatory resources/functionality from
one or more suppliers. A waiting_for_suppliers list is created to track
such consumers and retry linking them when new devices get added.

6cfae0c26b Char/Misc driver patches for 5.4-rc1
Here is the big char/misc driver pull request for 5.4-rc1.
 
 As has been happening in previous releases, more and more individual
 driver subsystem trees are ending up in here.  Now if that is good or
 bad I can't tell, but hopefully it makes your life easier as it's more
 of an aggregation of trees together to one merge point for you.
 
 Anyway, lots of stuff in here:
 	- habanalabs driver updates
 	- thunderbolt driver updates
 	- misc driver updates
 	- coresight and intel_th hwtracing driver updates
 	- fpga driver updates
 	- extcon driver updates
 	- some dma driver updates
 	- char driver updates
 	- android binder driver updates
 	- nvmem driver updates
 	- phy driver updates
 	- parport driver fixes
 	- pcmcia driver fix
 	- uio driver updates
 	- w1 driver updates
 	- configfs fixes
 	- other assorted driver updates

Pull char/misc driver updates from Greg KH:
 "Here is the big char/misc driver pull request for 5.4-rc1.

  As has been happening in previous releases, more and more individual
  driver subsystem trees are ending up in here. Now if that is good or
  bad I can't tell, but hopefully it makes your life easier as it's more
  of an aggregation of trees together to one merge point for you.

  Anyway, lots of stuff in here:
     - habanalabs driver updates
     - thunderbolt driver updates
     - misc driver updates
     - coresight and intel_th hwtracing driver updates
     - fpga driver updates
     - extcon driver updates

e444d51b14 TTY/Serial driver changes for 5.4-rc1
Even in this age, people are still making new serial port silicon,
 why...
 
 Anyway, here's the TTY and Serial driver update for 5.4-rc1.  Lots of
 changes in here for a number of embedded serial port devices that are
 being worked on because people really like to see those console logs...
 
 Other than that, nothing major here, no core tty changes that anyone
 should care about.

1f7d290a72 Driver core patches for 5.4-rc1
Here is the big driver core update for 5.4-rc1.
 
 There was a bit of a churn in here, with a number of core and OF
 platform patches being added to the tree, and then after much discussion
 and review and a day-long in-person meeting, they were decided to be
 reverted and a new set of patches is currently being reviewed on the
 mailing list.
 
 Other than that churn, there are two "persistent" branches in here that
 other trees will be pulling in as well during the merge window.  One
 branch to add support for drivers to have the driver core automatically
 add sysfs attribute files when a driver is bound to a device so that the
 driver doesn't have to manually do it (and then clean it up, as it
 always gets it wrong).
 
 There's another branch in here for generic lookup helpers for the driver
 core that lots of busses are starting to use.  That's the majority of
 the non-driver-core changes in this patch series.
 
 There's also some on-going debugfs file creation cleanup that has been
 slowly happening over the past few releases, with the goal to hopefully
 get that done sometime next year.
 
 All of these have been in linux-next for a while now with no reported
 issues.

  - We finally got around to zapping the documentation for hardware support

fdd61a013a gpio: Add support for hierarchical IRQ domains
Hierarchical IRQ domains can be used to stack different IRQ
controllers on top of each other.

Bring hierarchical IRQ domains into the GPIOLIB core with the
following basic idea:

Drivers that need their interrupts handled hierarchically
specify a callback to translate the child hardware IRQ and
IRQ type for each GPIO offset to a parent hardware IRQ and
parent hardware IRQ type.

Users have to pass the callback, fwnode, and parent irqdomain
before calling gpiochip_irqchip_add().

We use the new method of just filling in the struct
gpio_irq_chip before adding the gpiochip for all hierarchical
irqchips of this type.

The code path for device tree is pretty straight-forward,
while the code path for old boardfiles or anything else will
be more convoluted requireing upfront allocation of the
interrupts when adding the chip.

One specific use-case where this can be useful is if a power
management controller has top-level controls for wakeup
interrupts. In such cases, the power management controller can
be a parent to other interrupt controllers and program
additional registers when an IRQ has its wake capability
enabled or disabled.

The hierarchical irqchip helper code will only be available
when IRQ_DOMAIN_HIERARCHY is selected to GPIO chips using
this should select or depend on that symbol. When using
hierarchical IRQs, the parent interrupt controller must
also be hierarchical all the way up to the top interrupt
controller wireing directly into the CPU, so on systems
that do not have this we can get rid of all the extra
code for supporting hierarchical irqs.

515db266a9 driver core: Remove device link creation limitation
If device_link_add() is called for a consumer/supplier pair with an
existing device link between them and the existing link's type is
not in agreement with the flags passed to that function by its
caller, NULL will be returned.  That is seriously inconvenient,
because it forces the callers of device_link_add() to worry about
what others may or may not do even if that is not relevant to them
for any other reasons.

It turns out, however, that this limitation can be made go away
relatively easily.

The underlying observation is that if DL_FLAG_STATELESS has been
passed to device_link_add() in flags for the given consumer/supplier
pair at least once, calling either device_link_del() or
device_link_remove() to release the link returned by it should work,
but there are no other requirements associated with that flag.  In
turn, if at least one of the callers of device_link_add() for the
given consumer/supplier pair has not passed DL_FLAG_STATELESS to it
in flags, the driver core should track the status of the link and act
on it as appropriate (ie. the link should be treated as "managed").
This means that DL_FLAG_STATELESS needs to be set for managed device
links and it should be valid to call device_link_del() or
device_link_remove() to drop references to them in certain
sutiations.

To allow that to happen, introduce a new (internal) device link flag
called DL_FLAG_MANAGED and make device_link_add() set it automatically
whenever DL_FLAG_STATELESS is not passed to it.  Also make it take
additional references to existing device links that were previously
stateless (that is, with DL_FLAG_STATELESS set and DL_FLAG_MANAGED
unset) and will need to be managed going forward and initialize
their status (which has been DL_STATE_NONE so far).

Accordingly, when a managed device link is dropped automatically
by the driver core, make it clear DL_FLAG_MANAGED, reset the link's
status back to DL_STATE_NONE and drop the reference to it associated
with DL_FLAG_MANAGED instead of just deleting it right away (to
allow it to stay around in case it still needs to be released
explicitly by someone).

With that, since setting DL_FLAG_STATELESS doesn't mean that the
device link in question is not managed any more, replace all of the
status-tracking checks against DL_FLAG_STATELESS with analogous
checks against DL_FLAG_MANAGED and update the documentation to
reflect these changes.

While at it, make device_link_add() reject flags that it does not
recognize, including DL_FLAG_MANAGED.

916f562fb2 This round of clk driver and framework updates is heavy on the driver update
side. The two main highlights in the core framework are the addition of an bulk
 clk_get API that handles optional clks and an extra debugfs file that tells the
 developer about the current parent of a clk.
 
 The driver updates are dominated by i.MX in the diffstat, but that is mostly
 because that SoC has started converting to the clk_hw style of clk
 registration. The next big update is in the Amlogic meson clk driver that
 gained some support for audio, cpu, and temperature clks while fixing some PLL
 issues. Finally, the biggest thing that stands out is the conversion of a large
 part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses
 less strings and more pointer comparisons to match clk parents and children up.
 
 In general, it looks like we have a lot of little fixes and tweaks here and
 there to clk data along with the normal addition of a handful of new drivers
 and a couple new core framework features.
 
 Core:
  - Add a 'clk_parent' file in clk debugfs
  - Add a clk_bulk_get_optional() API (with devm too)
 
 New Drivers:
  - Support gated clk controller on MIPS based BCM63XX SoCs
  - Support SiLabs Si5341 and Si5340 chips
  - Support for CPU clks on Raspberry Pi devices
  - Audsys clock driver for MediaTek MT8516 SoCs
 
 Updates:
  - Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
  - Small frequency support for SiLabs Si544 chips
  - Slow clk support for AT91 SAM9X60 SoCs
  - Remove dead code in various clk drivers (-Wunused)
  - Support for Marvell 98DX1135 SoCs
  - Get duty cycle of generic pwm clks
  - Improvement in mmc phase calculation and cleanup of some rate defintions
  - Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
  - Add GPIO, SNVS and GIC clocks for i.MX8 drivers
  - Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
  - Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
  - Add clks for new Exynos5422 Dynamic Memory Controller driver
  - Clock definition for Exynos4412 Mali
  - Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
  - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
  - Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
  - TI clock probing done from DT by default instead of firmware
  - Fix Amlogic Meson mpll fractional part and spread sprectrum issues
  - Add Amlogic meson8 audio clocks
  - Add Amlogic g12a temperature sensors clocks
  - Add Amlogic g12a and g12b cpu clocks
  - Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N
  - Add CMM (Color Management Module) clocks on Renesas R-Car M3-W
  - Add Clock Domain support on Renesas RZ/N1

f632a8170a Driver Core and debugfs changes for 5.3-rc1
Here is the "big" driver core and debugfs changes for 5.3-rc1
 
 It's a lot of different patches, all across the tree due to some api
 changes and lots of debugfs cleanups.  Because of this, there is going
 to be some merge issues with your tree at the moment, I'll follow up
 with the expected resolutions to make it easier for you.
 
 Other than the debugfs cleanups, in this set of changes we have:
 	- bus iteration function cleanups (will cause build warnings
 	  with s390 and coresight drivers in your tree)
 	- scripts/get_abi.pl tool to display and parse Documentation/ABI
 	  entries in a simple way
 	- cleanups to Documenatation/ABI/ entries to make them parse
 	  easier due to typos and other minor things
 	- default_attrs use for some ktype users
 	- driver model documentation file conversions to .rst
 	- compressed firmware file loading
 	- deferred probe fixes
 
 All of these have been in linux-next for a while, with a bunch of merge
 issues that Stephen has been patient with me for.  Other than the merge
 issues, functionality is working properly in linux-next :)

97ff4ca46d Char / Misc driver patches for 5.3-rc1
Here is the "large" pull request for char and misc and other assorted
 smaller driver subsystems for 5.3-rc1.
 
 It seems that this tree is becoming the funnel point of lots of smaller
 driver subsystems, which is fine for me, but that's why it is getting
 larger over time and does not just contain stuff under drivers/char/ and
 drivers/misc.
 
 Lots of small updates all over the place here from different driver
 subsystems:
   - habana driver updates
   - coresight driver updates
   - documentation file movements and updates
   - Android binder fixes and updates
   - extcon driver updates
   - google firmware driver updates
   - fsi driver updates
   - smaller misc and char driver updates
   - soundwire driver updates
   - nvmem driver updates
   - w1 driver fixes

Merge tag 'char-misc-5.3-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc

Pull char / misc driver updates from Greg KH:
 "Here is the "large" pull request for char and misc and other assorted
  smaller driver subsystems for 5.3-rc1.

  It seems that this tree is becoming the funnel point of lots of
  smaller driver subsystems, which is fine for me, but that's why it is
  getting larger over time and does not just contain stuff under
  drivers/char/ and drivers/misc.

  Lots of small updates all over the place here from different driver
  subsystems:
   - habana driver updates
   - coresight driver updates
   - documentation file movements and updates
   - Android binder fixes and updates
   - extcon driver updates
   - google firmware driver updates
   - fsi driver updates
   - smaller misc and char driver updates
   - soundwire driver updates
   - nvmem driver updates
   - w1 driver fixes

  All of these have been in linux-next for a while with no reported
  issues"

e9a83bd232 It's been a relatively busy cycle for docs:
- A fair pile of RST conversions, many from Mauro.  These create more
    than the usual number of simple but annoying merge conflicts with other
    trees, unfortunately.  He has a lot more of these waiting on the wings
    that, I think, will go to you directly later on.
 
  - A new document on how to use merges and rebases in kernel repos, and one
    on Spectre vulnerabilities.
 
  - Various improvements to the build system, including automatic markup of
    function() references because some people, for reasons I will never
    understand, were of the opinion that :c:func:``function()`` is
    unattractive and not fun to type.
 
  - We now recommend using sphinx 1.7, but still support back to 1.4.
 
  - Lots of smaller improvements, warning fixes, typo fixes, etc.

 - Major overhaul and hardening of the OMAP driver by Russell

 - Starting to move some drivers to the new API passing irq_chip
   along with the gpio_chip when adding the gpio_chip instead
   of adding it separately.

Merge tag 'gpio-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the big slew of GPIO changes for the v5.3 kernel cycle. This
  is mostly incremental work this time.

  Three important things:

   - The FMC subsystem is deleted through my tree. This happens through
     GPIO as its demise was discussed in relation to a patch decoupling
     its GPIO implementation from the standard way of handling GPIO. As
     it turns out, that is not the only subsystem it reimplements and
     the authors think it is better do scratch it and start over using
     the proper kernel subsystems than try to polish the rust shiny. See
     the commit (ACKed by the maintainers) for details.

   - Arnd made a small devres patch that was ACKed by Greg and goes into
     the device core.

   - SPDX header change colissions may happen, because at times I've
     seen that quite a lot changed during the -rc:s in regards to SPDX.
     (It is good stuff, tglx has me convinced, and it is worth the
     occasional pain.)

  Apart from this is is nothing controversial or problematic.

  Summary:

  Core:

   - When a gpio_chip request GPIOs from itself, it can now fully
     control the line characteristics, both machine and consumer flags.
     This makes a lot of sense, but took some time before I figured out
     that this is how it has to work.

   - Several smallish documentation fixes.

  New drivers:

   - The PCA953x driver now supports the TI TCA9539.

   - The DaVinci driver now supports the K3 AM654 SoCs.

  Driver improvements:

   - Major overhaul and hardening of the OMAP driver by Russell King.

     with the gpio_chip when adding the gpio_chip instead of adding it
     separately.

1758feddb0 s390 updates for the 5.3 merge window
- Improve stop_machine wait logic: replace cpu_relax_yield call in generic
    stop_machine function with a weak stop_machine_yield function. This is
    overridden on s390, which yields the current cpu to the neighbouring cpu
    after a couple of retries, instead of blindly giving up the cpu to the
    hipervisor. This significantly improves stop_machine performance on s390 in
    overcommitted scenarios.
    This includes common code changes which have been Acked by Peter Zijlstra
    and Thomas Gleixner.
 
  - Improve jump label transformation speed: transform jump labels without
    using stop_machine.
 
  - Refactoring of the vfio-ccw cp handling, simplifying the code and
    avoiding unneeded allocating/copying.
 
  - Various vfio-ccw fixes (ccw translation, state machine).
 
  - Add support for vfio-ap queue interrupt control in the guest.
    This includes s390 kvm changes which have been Acked by Christian
    Borntraeger.
 
  - Add protected virtualization support for virtio-ccw.
 
  - Enforce both CONFIG_SMP and CONFIG_HOTPLUG_CPU, which allows to remove some
    code which most likely isn't working at all, besides that s390 didn't even
    compile for !CONFIG_SMP.
 
  - Support for special flagged EP11 CPRBs for zcrypt.
 
  - Handle PCI devices with no support for new MIO instructions.
 
  - Avoid KASAN false positives in reworked stack unwinder.
 
  - Couple of fixes for the QDIO layer.
 
  - Convert s390 specific documentation to ReST format.
 
  - Let s390 crypto modules return -ENODEV instead of -EOPNOTSUPP if hardware is
    missing. This way our modules behave like most other modules and which is
    also what systemd's systemd-modules-load.service expects.
 
  - Replace defconfig with performance_defconfig, so there is one config file
    less to maintain.
 
  - Remove the SCLP call home device driver, which was never useful.
 
  - Cleanups all over the place.

Convert the various documents at the driver-model, preparing
them to be part of the driver-api book.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to

page->mapping will be re-used by slab allocations and page->mapping->host

it's not an inode in fact and leads an oops.

According another commit 5e901d0b15 ("scsi: qedi: Fix bad pte call trace
when iscsiuio is stopped."), using kmalloc also cause other problem.

But the documentation about UIO_MEM_LOGICAL allows using kmalloc(), remove
and don't allow using kmalloc() in documentation.

28aedd7ee2 docs: pps.txt: convert to ReST and rename to pps.rst
This file is already in a good shape: just its title and
adding some literal block markups is needed for it to be
part of the document.

While it has a small chapter with sysfs stuff, most of
the document is focused on driver development.

As it describes a kernel API, move it to the driver-api
directory.

In order to avoid conflicts, let's add an :orphan: tag
to it, to be removed when added to the driver-api book.
