6852215a32 ARM: DRA7: id: Add cpu detection support for DRA7xx based SoCs'
The DRA7xx is a high-performance, infotainment application device,
based on enhanced OMAP architecture integrated on a 28-nm technology.

Since DRA7 is a platform supported only using DT, the cpu detection
is based on the compatibles passed from DT blobs as suggested here

21884a83b2 Merge branch 'timers-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer core updates from Thomas Gleixner:
 "The timer changes contain:

   - posix timer code consolidation and fixes for odd corner cases

   - sched_clock implementation moved from ARM to core code to avoid
     duplication by other architectures

   - alarm timer updates

   - clocksource and clockevents unregistration facilities

   - clocksource/events support for new hardware

   - precise nanoseconds RTC readout (Xen feature)

   - generic support for Xen suspend/resume oddities

   - the usual lot of fixes and cleanups all over the place

  The parts which touch other areas (ARM/XEN) have been coordinated with
  the relevant maintainers.  Though this results in an handful of
  trivial to solve merge conflicts, which we preferred over nasty cross
  tree merge dependencies.

  The patches which have been committed in the last few days are bug
  fixes plus the posix timer lot.  The latter was in akpms queue and
  next for quite some time; they just got forgotten and Frederic
  collected them last minute."

0bf6a210a4 ARM SoC driver specific changes
These changes are all driver specific and cross over between arm-soc
 contents and some other subsystem, in these cases cpufreq, crypto,
 dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
 have these changes merged through arm-soc. As we proceed to untangle
 the dependencies between platform code and driver code, the amount of
 changes in this category is fortunately shrinking, for 3.11 we have
 16 branches here and 101 non-merge changesets, the majority of which
 are for the stedma40 dma engine driver used in the ux500 platform.
 Cleaning up that code touches multiple subsystems, but gets rid
 of the dependency in the end.
 
 The mailbox code moved out from mach-omap2 to drivers/mailbox
 is an intermediate step and is still omap specific at the moment.
 Patches exist to generalize the subsystem and add other drivers
 with the same API, but those did not make it for 3.11.
 
 Conflicts:
 * In cpu-db8500.c results from the removal of the u8500_of_init_devices
   function in combination with the split of u8500_auxdata_lookup.
 
 * In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
   we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.

40e71e7015 ARM SoC board specific changes
These are 18 branches on 9 platforms with board specific changes, mostly
 for defconfig files, but nothing really exciting in here.
 
 Since the shmobile platform still uses board files for some of the newer
 machines, we get a few changes there as the result of drivers getting
 enabled for those boards. This causes some conflicts with contents getting
 added from multiple branches in sh-mobile specific files. Renesas is
 putting a lot of work into migrating to device-tree based setup, which
 will make all those files obsolete in the future and avoid both the
 conflicts and the need to have these files in the first place.

bf2920aa57 ARM: OMAP1: Remove duplicated DMA channel definitions
Similarly than with OMAP2 there are many DMA channel definitions that have
been moved or redefined in drivers using them and we can remove them from
dma.h.

There is exception with MMC that arch/arm/mach-omap1/devices.c is using
MMC DMA channel definitions for setting platform data but those can be well
replaced with numeric values.

Remove dma.h include from arch/arm/mach-omap1/devices.c and use a script
below for dropping duplicated definitions and for replacing definitions
with DMA channel numbers.

grep '#define OMAP_DMA' arch/arm/mach-omap1/dma.h | while read -r i; do \

c869c75c16 mailbox/omap: move the OMAP mailbox framework to drivers
The mailbox hardware (in OMAP) uses a queued mailbox interrupt
mechanism that provides a communication channel between processors
through a set of registers and their associated interrupt signals
by sending and receiving messages.

The OMAP mailbox framework/driver code is moved to be under
drivers/mailbox, in preparation for adapting to a common mailbox
driver framework. This allows the build for OMAP mailbox to be
enabled (it was disabled during the multi-platform support).

As part of the migration from plat and mach code:
- Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
- mailbox.h under plat-omap/plat/include has been split into a public
  and private header files. The public header has only the API related
  functions and types.
- The module name mailbox.ko from plat-omap is changed to
  omap-mailbox.ko
- The module name mailbox_mach.ko from mach-omapX is changed as
    mailbox_omap1.ko for OMAP1
    mailbox_omap2.ko for OMAP2+

a7726350e0 ARM: arm-soc cleanup for 3.10
Here is a collection of cleanup patches. Among the pieces that stand out are:
 
 - The deletion of h720x platforms
 - Split of at91 non-dt platforms to their own Kconfig file to keep them separate
 - General cleanups and refactoring of i.MX and MXS platforms
 - Some restructuring of clock tables for OMAP
 - Convertion of PMC driver for Tegra to dt-only
 - Some renames of sunxi -> sun4i (Allwinner A10)
 - ... plus a bunch of other stuff that I haven't mentioned

Here is a collection of fixes (and some intermixed cleanups) that were
 considered less important and thus not included in the later parts of

 It's a bit all over the map, contents wise. A series of ux500 fixes
 and cleanups, a bunch of various fixes for OMAP and tegra, and some for
 Freescale i.MX and even Qualcomm MSM.
 
 Note that there's also a patch on this branch to globally turn off

 to pick it up. So here it is, as the topmost patch.

13872ebb91 ARM: OMAP1: fix USB host on 1710
There is a long-standing bug that OHCI USB host controller does
not respond on 1710, because of wrong clock definitions. See e.g.
http://marc.info/?l=linux-omap&m=119634441229321&w=2. All register reads
return just zeroes:

[    1.896606] ohci ohci: OMAP OHCI
[    1.912597] ohci ohci: new USB bus registered, assigned bus number 1
[    1.933776] ohci ohci: irq 38, io mem 0xfffba000
[    2.012573] ohci ohci: init err (00000000 0000)

[    2.046661] ohci ohci: startup error -75
[    2.063201] ohci ohci: USB bus 1 deregistered

After some experiments, it seems that when changing the usb_dc_ck /
SOFT_REQ enable bit from USB_REQ_EN_SHIFT to SOFT_USB_OTG_DPLL_REQ_SHIFT
(like done also on 7XX), the USB appears to work:

[    2.183959] ohci ohci: OMAP OHCI
[    2.198242] ohci ohci: new USB bus registered, assigned bus number 1
[    2.215820] ohci ohci: irq 38, io mem 0xfffba000
[    2.324798] hub 1-0:1.0: USB hub found
[    2.361267] hub 1-0:1.0: 3 ports detected

Commit 16559ae4 (kgdb: remove #include <linux/serial_8250.h> from kgdb.h)
had a side effect of breaking omap1_defconfig build as some headers
were included indirectly:

arch/arm/mach-omap1/board-h2.c:249: error: ‘INT_KEYBOARD’ undeclared here (not in a function)
...

This worked earlier as linux/serial_8250.h included linux/serial_core.h,

3298a3511f arm-soc: multiplatform support
Converting more ARM platforms to multiplatform support. This time, OMAP
 gets converted, which is a major step since this is by far the largest
 platform in terms of code size. The same thing happens to the vt8500
 platform.
 
 Conflicts include:
 * Two mach/uncompress.h files are removed, the changes made to them
   elsewhere can be discarded now.
 * Moving the OMAP4 irq_match array has context clashes with turning
   omap4_sar_ram_init into an omap_early_initcall()

974b33586b ARM: arm-soc fixes for 3.8-rc
People are back from the holiday breaks, and it shows. Here are a bunch of
 fixes for a number of platforms:
  - A couple of small fixes for Nomadik
  - A larger set of changes for kirkwood/mvebu
    - uart driver selection, dt clocks, gpio-poweroff fixups,
      a few __init annotation fixes and some error handling improvement
      in their xor dma driver.
  - i.MX had a couple of minor fixes (and a critical one for flexcan2
    clock setup)
  - MXS has a small board fix and a framebuffer bugfix
  - A set of fixes for Samsung Exynos, fixing default bootargs and some
    Exynos5440 clock issues
  - A set of OMAP changes including PM fixes and a few sparse warning
    fixups
 
 All in all a bit more positive code delta than we'd ideally want to see
 here, mostly from the OMAP PM changes, but nothing overly crazy.

981302783e ARM/...: timer and clock events cleanup, and remove struct sys_timer
This branch contains a number of cleanups and unifications to various
 timer- clock-events- and ARM timer code. The main points are:
 
 1) Convert arch_gettimeoffset to a pointer, so that architectures with
    multiple timer implementations can simply set this standard pointer
    rather than maintaining their own arch-specific pointers for the
    same purpose. Various architectures are converted to using this new
    feature.
 
 2) Conversion of ARM timer implementations to use clock_event_devices's
    suspend/resume operations, rather than the ARM-specific sys_timer
    versions. Thus, the ARM code begins to use more common infra-structure
    rather than arch-specific code.
 
 3) Removal of ARM's struct sys_timer completely, now that everything uses
    common code.
 
 4) Introduction of drivers/clocksource/clksrc-of.c, which allows ARM clock
    source implementations to be moved into drivers/clocksource, with the
    need to add SoC-specific header files for each timer initialization
    function; instead, all enabled implementations are registered into a
    table which a single core function iterates over, and calls the
    relevant initialization functions based on device tree. At least the
    Tegra and BCM2835 clocksource implementations will use this feature in
    the 3.9 kernel cycle.

351a102dbf ARM: drivers: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

8d91a42e54 ARM: arm-soc: late cleanups for omap
From Tony Lindgren:
 Here are few more patches to finish the omap changes for
 multiplatform conversion that are not strictly fixes, but
 were too complex to do with the dependencies during the
 merge window. Those are to move of serial-omap.h to
 platform_data, and the removal of remaining cpu_is_omap
 macro usage outside mach-omap2.
 
 Then there are several trivial fixes for typos and few
 minimal omap2plus_defconfig updates.

6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

16d60bb86e ARM: OMAP: Split fb.c to remove last remaining cpu_is_omap usage
Looks like we missed plat-omap/fb.c for cpu_is_omap usage
mach-omap2. This is the last user of cpu_is_omap, so let's
quickly fix it up so we can finally remove plat/cpu.h for
omap2lus.

We want to limit cpu_is_omap macro usage to mach-omap2 only so
we can make plat/cpu.h private. After this we can finally drop
plat/cpu.h for omap2+.

a11da7df65 ARM: arm-soc: power management and clock changes
This branch contains a largeish set of updates of power management and
 clock setup. The bulk of it is for OMAP/AM33xx platforms, but also a
 few around hotplug/suspend/resume on Exynos.
 
 It includes a split-up of some of the OMAP clock data into separate
 files which adds to the diffstat, but gross delta is fairly reasonable.
