Benoit Cousson d9120198dd clk: shmobile: rcar-gen2: Use kick bit to allow Z clock frequency change
The Z clock frequency change is effective only after setting the kick
bit located in the FRQCRB register.
Without that, the CA15 CPUs clock rate will never change.

Fix that by checking if the kick bit is cleared and enable it to make
the clock rate change effective. The bit is cleared automatically upon
completion.

Linus Walleij ec6deea1a1 clk: nomadik: fix multiplatform problem
The Nomadik debugfs screws up multiplatform boots if debugfs
is enabled on the multiplatform image, since it's a simple
initcall that is unconditionally executed and reads from certain
memory locations.

Fix this by checking that the driver has been properly
initialized, so a base offset to the Nomadik SRC controller
exists, before proceeding to register debugfs files.

The clk_init_data struct is allocated in the stack. All members of
this struct should be initialized before using otherwise it will
lead to unpredictable situation as it can contain garbage.

Ultimately the clk->flag field contains garbage. In my case it leads
that flag CLK_IGNORE_UNUSED is set for most of clocks. As result a
bunch of unused clocks cannot be disabled.

So initialize flags in this structure too.

Commit 9807362bfe
  "clk: si5351: declare all device IDs for module loading"
removed the common i2c_device_id and introduced new ones for each variant
of the clock generator. Instead of exploiting that information in the driver,
it still depends on platform_data passing the chips .variant.

This removes the now redundant .variant from the platform_data and puts it in
i2c_device_id's .driver_data instead.

Linus Torvalds 7e21774db5 The first half of the clk framework pull request is made up almost
entirely of new platform/driver support. There are some conversions of
 existing drivers to the common-clock Device Tree binding, and a few
 non-critical fixes to the framework.
 
 Due to an entirely unnecessary cyclical dependency with the arm-soc tree
 this pull request is broken into two pieces. The second piece will be
 sent out after arm-soc sends you the pull request that merged in core
 support for the HiSilicon 3620 platform. That same pull request from
 arm-soc depends on this pull request to merge in those HiSilicon bits
 without causing build failures.

  non-critical fixes to the framework.

  Due to an entirely unnecessary cyclical dependency with the arm-soc
  tree this pull request is broken into two pieces.  The second piece
  will be sent out after arm-soc sends you the pull request that merged
  in core support for the HiSilicon 3620 platform.  That same pull
  request from arm-soc depends on this pull request to merge in those
  HiSilicon bits without causing build failures"

Linus Torvalds 0ba3307a8e ARM: driver updates for 3.14
Updates of SoC-near drivers and other driver updates that makes more sense to
 take through our tree.
 
 The largest part of this is a conversion of device registration for some
 renesas shmobile/sh devices over to use resources. This has required
 coordination with the corresponding arch/sh changes, and we've agreed
 to merge the arch/sh changes through our tree.
 
 Added in this branch is support for Trusted Foundations secure firmware,
 which is what is used on many of the commercial Nvidia Tegra products
 that are in the market, including the Nvidia Shield. The code is local
 to arch/arm at this time since it's uncertain whether it will be shared
 with arm64 longer-term, if needed we will refactor later.
 
 A couple of new RTC drivers used on ARM boards, merged through our tree
 on request by the RTC maintainer.
 
 ... plus a bunch of smaller updates across the board, gpio conversions
 for davinci, etc.

Linus Torvalds 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.

Linus Torvalds 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

 enough to warrant going into the later -rcs for previous release, so

 There are also a couple of stable-marked patches for mvebu -- they came in
 quite late and we decided to keep them deferred until the first -stable
 release to get more coverage instead of squeezing them into 3.13.

Tero Kristo 6a369c584f clk: ti: add support for basic mux clock
ti,mux-clock provides now a binding for basic mux support. This is just
using the basic clock type.

Tero Kristo 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.
