92ca6a8ce9 clk: emev2: Add support for emev2 SMU clocks with DT
Device tree clock binding document for EMMA Mobile EV2 SMU,
And Common clock framework based implementation of it.
Following nodes are defined to describe clock tree.
- renesas,emev2-smu
- renesas,emev2-smu-clkdiv
- renesas,emev2-smu-gclk

These bindings are designed manually based on
 19UH0037EJ1000_SMU : System Management Unit User's Manual

So far, reparent is not implemented, and is fixed to index #0.
Clock tree description is not included, and should be provided
by device-tree.

f94859c215 clk: shmobile: Add MSTP clock support
MSTP clocks are gate clocks controlled through a register that handles
up to 32 clocks. The register is often sparsely populated.

Those clocks are found on Renesas ARM SoCs.

abe844aa5b clk: shmobile: Add DIV6 clock support
DIV6 clocks are divider gate clocks controlled through a single
register. The divider is expressed on 6 bits, hence the name, and can
take values from 1/1 to 1/64.

Those clocks are found on Renesas ARM SoCs.

10cdfe9f32 clk: shmobile: Add R-Car Gen2 clocks support
The R-Car Gen2 SoCs (R8A7790 and R8A7791) have several clocks that are
too custom to be supported in a generic driver. Those clocks can be
divided in two categories:

- Fixed rate clocks with multiplier and divisor set according to boot
  mode configuration

- Custom divider clocks with SoC-specific divider values

This driver supports both.

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.

 - Marvell mvebu patches for PCI MSI support (could have gone through the PCI

b4b50fd78b ARM: SoC platform changes for 3.12
This branch contains mostly additions and changes to platform enablement
 and SoC-level drivers. Since there's sometimes a dependency on device-tree
 changes, there's also a fair amount of those in this branch.
 
 Pieces worth mentioning are:
 
 - Mbus driver for Marvell platforms, allowing kernel configuration
   and resource allocation of on-chip peripherals.
 - Enablement of the mbus infrastructure from Marvell PCI-e drivers.
 - Preparation of MSI support for Marvell platforms.
 - Addition of new PCI-e host controller driver for Tegra platforms
 - Some churn caused by sharing of macro names between i.MX 6Q and 6DL
   platforms in the device tree sources and header files.
 - Various suspend/PM updates for Tegra, including LP1 support.
 - Versatile Express support for MCPM, part of big little support.
 - Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
 - OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
 
 The code that touches other architectures are patches moving
 MSI arch-specific functions over to weak symbols and removal of
 ARCH_SUPPORTS_MSI, acked by PCI maintainers.

The Allwinner A20 is almost identical to the earlier A10 SoC from
Allwinner on many aspects, including the clocks tree. However, since the
A20 has some additionnal IPs compared to the A10, the clock tree isn't
exactly the same, especially when it comes to the gated clocks

42daabf62b ARM SoC late changes
These are changes that arrived a little late before the merge
 window or that have multiple dependencies on previous branches
 so they did not fit into one of the earlier ones. There
 are 10 branches merged here, a total of 39 non-merge commits.
 Contents are a mixed bag for the above reasons:
 
 * Two new SoC platforms: ST microelectronics stixxxx and
   the TI 'Nspire' graphing calculator. These should have
   been in the 'soc' branch but were a little late
 * Support for the Exynos 5420 variant in mach-exynos,
   which is based on the other exynos branches to avoid
   conflicts.
 * Various small changes for sh-mobile, ux500 and davinci
 * Common clk support for MSM
 
 Conflicts:
 * In Kconfig.debug, various additions trivially conflict,
   the list should be kept in alphabetical order when
   resolving.

Merge tag 'late-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC late changes from Arnd Bergmann:
 "These are changes that arrived a little late before the merge window
  or that have multiple dependencies on previous branches so they did
  not fit into one of the earlier ones.  There are 10 branches merged
  here, a total of 39 non-merge commits.  Contents are a mixed bag for
  the above reasons:

   * Two new SoC platforms: ST microelectronics stixxxx and the TI
     'Nspire' graphing calculator.  These should have been in the 'soc'
     branch but were a little late
   * Support for the Exynos 5420 variant in mach-exynos, which is based
     on the other exynos branches to avoid conflicts.
   * Various small changes for sh-mobile, ux500 and davinci
   * Common clk support for MSM"

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.

ee1a8d402e ARM SoC device tree changes
These changes from 30 individual branches for the most part update device
 tree files, but there are also a few source code changes that have crept
 in this time, usually in order to atomically move over a driver from
 using hardcoded data to DT probing.
 
 A number of platforms change their DT files to use the C preprocessor,
 which is causing a bit of churn, but that is hopefully only this once.
 
 There are a few conflicts with the other branches unfortunately:
 
 * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
   from multiple branches. Need to be careful to have the right
   set of closing braces as git gets this one wrong.
 
 * In kirkwood.dtsi, one 'ranges' line got split into two lines, while
   another line got added. Order of the lines does not matter.
 
 * in sama5d3.dtsi, some cleanup was merged the wrong way, causing
   a bogus conflict. We want the 'dmas' and 'dma-names' properties
   to get added here.
 
 * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
 
 * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

646572c77d clk: add support for Rockchip gate clocks
This adds basic support for gate-clocks on Rockchip SoCs.
There are 16 gates in each register and use the HIWORD_MASK
mechanism for changing gate settings.

The gate registers form a continuos block which makes the dt node
structure a matter of taste, as either all 160 gates can be put into
one gate clock spanning all registers or they can be divided into
the 10 individual gates containing 16 clocks each.
The code supports both approaches.
