6520e968ee clk: exynos5420: Add 5800 specific clocks
Exynos5800 clock structure is mostly similar to 5420 with only
a small delta changes. So the 5420 clock file is re-used for
5800 also. The common clocks for both are seggreagated and few
clocks which are different for both are separately initialized.

The next patch defines a binding for a new Broadcom SoC that uses
Kona style CCUs for its clocks.  Update the generic Kona clock
binding document so it's more natural to accomodate the definitions
of additional SoC families.

Specifically:
    - Define the compatible string values generically, referring
      to specific per-model values later in the document.
    - Put the device tree example immediately after the required
      properties listing, before the tables of SoC-specific values.
    - Clearly identify the start of the section defining specific
      values related to the BCM281XX family
    - Add a list of the specific BCM281XX family compatible strings.
    - Reword the description of the table slightly.

This commit adds a core clock driver for the Orion5x SoC, with support
for the tclk, the CPU frequency and the DDR frequency. All the details
about the Sample-At-Reset register were extracted from the U-Boot
sources for Orion5x.

Note that Orion5x does not have gatable clocks, so this core clock
driver is sufficient to support clocking on Orion5x platforms.

 "These could not be part of the first cleanup branch, because they
  either came too late in the cycle, or they have dependencies on other
  branches.  Important changes are:

   - The integrator platform is almost multiplatform capable after some
     reorganization (Linus Walleij)
   - Minor cleanups on Zynq (Michal Simek)
   - Lots of changes for Exynos and other Samsung platforms, including
     further preparations for multiplatform support and the clocks
     bindings are rearranged"

cbda94e039 ARM: SoC: driver changes
These changes are mostly for ARM specific device drivers that either
 don't have an upstream maintainer, or that had the maintainer ask
 us to pick up the changes to avoid conflicts. A large chunk of this
 are clock drivers (bcm281xx, exynos, versatile, shmobile), aside from
 that, reset controllers for STi as well as a large rework of the
 Marvell Orion/EBU watchdog driver are notable.

f83ccb9358 ARM: SoC: device tree changes
A large part of the arm-soc patches are nowadays DT changes, adding support
 for new SoCs, boards and devices without changing kernel source. The plan
 is still to move the devicetree files out of the kernel tree and reduce
 the amount of churn going on here, but we keep finding reasons to delay
 doing that.
 
 Changes are really all over the place, with little sticking out particularly.
 We have contributions from a total of 116 people in this branch.
 
 Unfortunately, the size of this branch also causes a significant number
 of conflicts at the moment, typically when subsystem maintainers merge
 patches that change the driver at the same time as the dts files. In
 most cases this could be avoided because the dts changes are supposed
 to be compatible in both ways, and we are asking everyone to send ARM
 dts changes through our tree only.

v9: none
v8: Use degrees in the clk-phase binding property
v7: Add dts property to represent the clk phase of the sdmmc_clk. Add a
    prepare function to the gate clk that will toggle clock phase setting.
    Remove the "altr,socfpga-sdmmc-sdr-clk" clock type.
v6: Add a new clock type "altr,socfpga-sdmmc-sdr-clk" that will be used to
    set the phase shift settings.
v5: Use the "snps,dw-mshc" binding
v4: Use the sdmmc_clk prepare function to set the phase shift settings
v3: Not use the syscon driver because as of 3.13-rc1, the syscon driver is
    loaded after the clock driver.
v2: Use the syscon driver

09c978bc7b ARM: integrator: switch to fetch clocks from device tree
This atomic commit changes the Integrator clock implementation
and the machines to register clocks from the device tree and
use these instead of the previous hard-coded clocks.

In the clock implementation all hard-coded clocks and the
special initialization function call goes away, and is
replaced by two compatible strings for the two clocks
available on the core module.

9b6d351a75 ARM: SoC DT updates for 3.14
DT and DT-conversion-related changes for various ARM platforms. Most
 of these are to enable various devices on various boards, etc, and not
 necessarily worth enumerating.
 
 New boards and systems continue to come in as new devicetree files that
 don't require corresponding C changes any more, which is indicating that
 the system is starting to work fairly well.
 
 A few things worth pointing out:
 
 * ST Ericsson ux500 platforms have made the major push to move over to fully
   support the platform with DT.
 * Renesas platforms continue their conversion over from legacy platform devices
   to DT-based for hardware description.

 "DT and DT-conversion-related changes for various ARM platforms.  Most
  of these are to enable various devices on various boards, etc, and not
  necessarily worth enumerating.

  New boards and systems continue to come in as new devicetree files
  that don't require corresponding C changes any more, which is
  indicating that the system is starting to work fairly well.

  A few things worth pointing out:

   * ST Ericsson ux500 platforms have made the major push to move over
     to fully support the platform with DT
   * Renesas platforms continue their conversion over from legacy
     platform devices to DT-based for hardware description"

f2c73464d7 ARM: SoC cleanups for 3.14
This is the branch where we usually queue up cleanup efforts, moving
 drivers out of the architecture directory, header file restructuring,
 etc. Sometimes they tangle with new development so it's hard to keep it
 strictly to cleanups.
 
 Some of the things included in this branch are:
 
 * Atmel SAMA5 conversion to common clock
 * Reset framework conversion for tegra platforms
  - Some of this depends on tegra clock driver reworks that are shared with Mike
    Turquette's clk tree.
 * Tegra DMA refactoring, which are shared branches with the DMA tree.
 * Removal of some header files on exynos to prepare for multiplatform

3cd4a59622 CLK: TI: add support for clockdomain binding
Some OMAP clocks require knowledge about their parent clockdomain for
book keeping purposes. This patch creates a new DT binding for TI
clockdomains, which act as a collection of device clocks. Clockdomain
itself is rather misleading name for the hardware functionality, as at
least on OMAP4 / OMAP5 / DRA7 the clockdomains can be collections of either
clocks and/or IP blocks, thus idle-domain or such might be more appropriate.
For most cases on these SoCs, the kernel doesn't even need the information
and the mappings can be ignored.

35399dda01 clk: exynos5250: add clock ID for div_pcm0
There is no gate for the PCM clock input to the AudioSS block, so
the parent of sclk_pcm is div_pcm0.  Add a clock ID for it so that
we can reference it in device trees.

497d2214e5 Samsung Clock fixes for 3.13-rc7
* Several patches fixing up incorrectly defined register addresses and
   bitfield offsets that could lead to undefined operation when accessing
   respective registers or bitfields.
 
  1) clk: exynos5250: fix sysmmu_mfc{l,r} gate clocks
 
  2a) clk: samsung: exynos5250: Fix ACP gate register offset
  2b) clk: samsung: exynos5250: Add MDMA0 clocks
  2c) ARM: dts: exynos5250: Fix MDMA0 clock number
 
  3) clk: samsung: exynos4: Correct SRC_MFC register
 
    All three issues have been present since Exynos5250 and Exynos4 clock
    drivers were added by commits 6e3ad26816 ("clk: exynos5250:
    register clocks using common clock framework") and e062b57177
    ("clk: exynos4: register clocks using common clock framework")
    respectively.
 
 * Patch to fix automatic disabling of Exynos5250 sysreg clock that could
   cause undefined operation of several peripherals, such as USB, I2C,
   MIPI or display block.
 
  4) clk: samsung: exynos5250: Add CLK_IGNORE_UNUSED flag for the sysreg
     clock
 
    Present since Exynos5250 clock drivers was added by commits
    6e3ad26816 ("clk: exynos5250: register clocks using common clock
    framework").
 
 * Patch fixing compilation warning in clk-exynos-audss driver when
   CONFIG_PM_SLEEP is disabled.
 
  5) clk: exynos: File scope reg_save array should depend on PM_SLEEP
 
    Present since the driver was added by commit 1241ef94cc ("clk:
    samsung: register audio subsystem clocks using common clock
    framework").
