Tero Kristo 944ee5dc15 ARM: OMAP2: convert sys_ck and osc_ck to standard clock types
osc_ck can be simply defined as a multiplexer clock, and the sys_ck
can be a simple divider.

Linus Torvalds d30492adea The second half of the clock framework pull requeust for 3.14 is
dominated by platform support for Qualcomm's MSM SoCs, DT binding
 updates for TI's OMAP-ish processors and additional support for Samsung
 chips. Additionally there are other smaller clock driver changes and
 several last minute fixes. This pull request also includes the HiSilicon
 support that depends on the already-merged arm-soc pull request.

Tony Lindgren 54ea18e886 ARM: OMAP2+: Remove board file for H4
The old 2420 based H4 is probably not used at all as 2420
was Nokia specific SoC. I have one, but I'm not using it because
of it's large size, and I doubt anybody else is using it either.

We do have minimal omap2420-h4.dts in place, so if anybody wants
more support on H4, patches are welcome.

So let's just remove it as that helps us making mach-omap2 to
be device tree only.

We need to check for AM43XX without any omap4 or 5 related
SoCs as well. And looks like we have prm44xx.o built always
anyways with omap-4-5-prcm-common because of the calls to

Linus Torvalds f9efbce633 ARM: SoC DT updates for 3.13
Most of this branch consists of updates, additions and general churn of
 the device tree source files in the kernel (arch/arm/boot/dts). Besides
 that, there are a few things to point out:
 
 - Lots of platform conversion on OMAP2+, with removal of old board files
   for various platforms.
 - Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
 - Some updates to pinctrl and other subsystems. Most of these are for
   DT-enablement of the various platforms and acks have been collected.

Linus Torvalds d5aabbcaee ARM: SoC board updates for 3.13

 Right now by far most of the code is related to shmobile updates, and
 they are now switching over to removal of board code and migration to
 multiplatform, so we'll see their board code base shrink in the near
 future too, I hope.
 
 In addition to that is some defconfig updates, some display updates for OMAP

Build AM43x power domain, clock domain and hwmod data.

Many of AM43x IP's and interconnects are similar as that in AM335x,
hence AM335x hwmod data is being reused with necessary changes.

Earlier the plan was to reuse AM335x specific PRCM code, but as AM43x
PRCM register layout is much similar to OMAP4/5, AM335x PRCM is
divorced and instead married with OMAP4/5 PRCM for AM43x.

AM335x and AM43x have most of the IP's and interconnect's similar.
Instead of adding redundant hwmod data, move interconnects and hwmod
similar between AM335x and AM43x to a common location. This helps in
reuse on AM43x.

AM335x interconnects that has difference and not present in AM43x are
not moved. ocp clock of those in l4_wkup is fed from a different source
for AM43x. Also pruss interconnect is different.

AM335x hwmod's that has difference other than prcm register offsets
(difference is in clocks of wkup_m3, control, gpio0, debugss and clock
domain of l4_hs, adc_tsc as compared to AM43x) and those that are not

R Sricharan bfe9211a30 ARM: DRA7: Reuse all of PRCM and MPUSS SMP infra
The PRCM and MPUSS parts of DRA7 devices are quite identical
to OMAP5 so as to reuse all the existing infrastructure around it.
Makefile updates to do just that.

Linus Torvalds 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.

Linus Torvalds 3883cbb6c1 ARM SoC specific changes
These changes are all to SoC-specific code, a total of 33 branches on
 17 platforms were pulled into this. Like last time, Renesas sh-mobile
 is now the platform with the most changes, followed by OMAP and EXYNOS.
 
 Two new platforms, TI Keystone and Rockchips RK3xxx are added in
 this branch, both containing almost no platform specific code at all,
 since they are using generic subsystem interfaces for clocks, pinctrl,
 interrupts etc. The device drivers are getting merged through the
 respective subsystem maintainer trees.
 
 One more SoC (u300) is now multiplatform capable and several others
 (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
 towards that goal with this series but need more work.
 
 Also noteworthy is the work on PCI here, which is traditionally part of
 the SoC specific code. With the changes done by Thomas Petazzoni, we can
 now more easily have PCI host controller drivers as loadable modules and
 keep them separate from the platform code in drivers/pci/host. This has
 already led to the discovery that three platforms (exynos, spear and imx)
 are actually using an identical PCIe host controller and will be able
 to share a driver once support for spear and imx is added.
 
 Conflicts:
 * asm/glue-proc.h has one CPU type getting added that conflicts
   with another addition in 3.10-rc7
 * Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

Suman Anna 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+

Arnd Bergmann 572b16db70 ARM: OMAP: build SMP code only for OMAP4/5
The OMAP platform code assumes that SMP is only ever enabled when
CONFIG_ARCH_OMAP4 or CONFIG_SOC_OMAP5 is enabled, which is not
necessarirly true in a multiplatform configuration.

Merge commit 952414505f ("Merge branch
'next/cleanup' of git://git.linaro.org/people/arnd/arm-soc") added
references to CONFIG_MACH_PCM049 and board-omap4pcm049.o to this
Makefile. But there's no Kconfig symbol MACH_PCM049 and there's no file
board-omap4pcm049.c. This line can safely be removed.

Linus Torvalds 7307c00f33 arm-soc: late OMAP changes
This branch contains changes for OMAP that came in late during the release
 staging, close to when the merge window opened.
 
 It contains, among other things:
 
 - OMAP PM fixes and some patches for audio device integration
 - OMAP clock fixes related to common clock conversion
 - A set of patches cleaning up WFI entry and blocking.
 - A set of fixes and IP block support for PM on TI AM33xx SoCs (Beaglebone, etc)
 - A set of smaller fixes and cleanups around AM33xx restart and revision
   detection, as well as removal of some dead code (CONFIG_32K_TIMER_HZ)

Paul Walmsley c02060d869 ARM: OMAP4+: AESS: enable internal auto-gating during initial setup
Enable the AESS auto-gating control bit during AESS hwmod setup.  This
fixes the following boot warning on OMAP4:

omap_hwmod: aess: _wait_target_disable failed

Without this patch, the AESS IP block does not indicate to the PRCM
that it is idle after it is reset.  This prevents some types of SoC
power management until something sets the auto-gating control bit.
