bef4a0ab98 The common clk framework changes for 3.12 are dominated by clock driver
patches, both new drivers and fixes to existing. A high percentage of
 these are for Samsung platforms like Exynos. Core framework fixes and
 some new features like automagical clock re-parenting round out the
 patches.

06dda9d770 clk: samsung: Add clock driver for S3C64xx SoCs
This patch adds new, Common Clock Framework-based clock driver for Samsung
S3C64xx SoCs. The driver is just added, without actually letting the
platforms use it yet, since this requires more intermediate steps.

4f71612ee3 ARM: imx: fix vf610 enet module clock selection
The fec/enet driver calculates MDC rate with the formula below.

  ref_freq / ((MII_SPEED + 1) x 2)

The ref_freq here is the fec internal module clock, which is missing
from clk-vf610 clock driver right now.  And clk-vf610 driver mistakenly
supplies RMII clock (50 MHz) as the source to fec.  This results in the
situation that fec driver gets ref_freq as 50 MHz, while physically it
runs at 66 MHz (fec module clock physically sources from ipg which runs
at 66 MHz).  That's why software expects MDC runs at 2.5 MHz, while the
measurement tells it runs at 3.3 MHz.  And this causes the PHY KSZ8041
keeps swithing between Full and Half mode as below.

  libphy: 400d0000.etherne:00 - Link is Up - 100/Full
  libphy: 400d0000.etherne:00 - Link is Up - 100/Half
  libphy: 400d0000.etherne:00 - Link is Up - 100/Full
  libphy: 400d0000.etherne:00 - Link is Up - 100/Half
  libphy: 400d0000.etherne:00 - Link is Up - 100/Full
  libphy: 400d0000.etherne:00 - Link is Up - 100/Half

Add the missing module clock for ENET0 and ENET1, and correct the clock
supplying in device tree to fix above issue.

Thanks to Alison Wang <b18965@freescale.com> for debugging the issue.

992bb598f6 ARM: tegra114: create a DT header defining CLK IDs
Create a header file to define the clock IDs used by the Tegra114 clock
binding. Remove the list of definitions from the binding documentation,
and refer the reader to the header file.

This will allow the same header to be used by both device tree files,
and drivers implementing this binding, which guarantees that the two
stay in sync. This also makes device trees more readable by using names
instead of magic numbers.
