04bc7d96fb clk: samsung: exynos4: Use single clock ID for CLK_MDMA gate clocks
Exynos4210 and Exynos4x12 SoCs have the PL330 MDMA IP block clock
defined exactly in same way in documentation. Using different
names for these clocks is a bit misleading. Since there is no users
of CLK_MDMA2 in existing dts files this patch drops CLK_MDMA2 and
replaces it with CLK_MDMA in the driver. This ensures PL330 MDMA
has correct clock assigned on Exynos4x12 SoCs.

976face4b4 clk/samsung: add support for multiple clock providers
Samsung CCF helper functions do not provide support to
register multiple Clock Providers for a given SoC. Due to
this limitation, SoC platforms are not able to use these
helpers for registering multiple clock providers and are
forced to bypass this layer.

This layer is modified accordingly to enable the support
for multiple clock providers.

Clock file for exynos4, exynos5250, exynos5420, exynos5440,
S3c64xx, S3c24xx are also modified as per changed helper functions.

3f7c01ade2 clk: samsung: add clock controller driver for s3c2410, s3c2440 and s3c2442
This driver can handle the clock controllers of the socs mentioned above,
as they share a common clock tree with only small differences.

The clock structure is built according to the manuals of the included
SoCs and might include changes in comparison to the previous clock
structure.

As pll-rate-tables only the 12mhz variants are currently included.
The original code was wrongly checking for 169mhz xti values [a 0 to much
at the end], so the original 16mhz pll table would have never been
included and its values are so obscure that I have no possibility to
at least check their sane-ness. When using the formula from the manual
the resulting frequency is near the table value but still slightly off.

5799ea12a4 clk: samsung: add clock driver for external clock outputs
This adds a driver for controlling the external clock outputs of
s3c24xx architectures including the dclk muxes and dividers.

The driver at the moment only supports the legacy non-dt boards using these
clock outputs. The clock-output control itself is part of the system-controller
mainly controlled by the pinctrl drivers. So it should most likely be
integrated there for dt platforms.

61fbb1d278 clk: samsung: add clock-driver for s3c2416, s3c2443 and s3c2450
The three SoCs share a common clock tree which only differs in the
existence of some special clocks.

As with all parts common to these three SoCs the driver is named
after the s3c2443, as it was the first SoC introducing this structure
and there exists no other label to describe this s3c24xx epoch.

The clock structure is built according to the manuals of the included
SoCs and might include changes in comparison to the previous clock
structure. As an example the sclk_uart gate was never handled previously
and the div_uart was made to be the clock used by the serial driver.

06654acb66 clk: samsung: add pll_6552 variant for s3c2416
According to the manual s3c2416 and s3c2450 use a pll 6552 and 6553
and while the pll_6553 matches exactly the one already implemented
the pll_6552 differs to the one from the s3c64xx series.

The change is solely in the bit locations of the mdiv and pdiv values.
All calculations are the same for both implementatons and even the
proposed divider-values for specific frequencies in the manuals are
the same.

Therefore implement a variant that simply uses the changed bit
locations if necessary.

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.

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.

93abdb7785 ARM: SoC non-critical fixes for 3.14
As usual, we have a batch of fixes that weren't considered significant
 enough to warrant going into the later -rcs for previous release, so
 they are queued up on this branch.
 
 A handful of these are for various DT fixups for Samsung platforms,
 and a handful of other minor things.
 
 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.

b37a422410 clk: exynos-audss: convert to platform device
The Exynos AudioSS clock controller will later be modified to allow
input clocks to be specified via device-tree in order to support
multiple Exynos SoCs.  This will introduce a dependency on the core
SoC clock controller being initialized first so that the AudioSS driver
can look up its input clocks, but the order in which clock providers
are probed in of_clk_init() is not guaranteed.  Since deferred probing
is not supported in of_clk_init() and the AudioSS block is not the core
controller, we can initialize it later as a platform device.
