Merge tag 'renesas-pinmux2-for-v3.10' into boards-base 

Second round of Renesas ARM and SH based SoC pinmux updates for v3.10

Highlights:

* Compilation fixes for sh7269 and for when CONFIG_BUG is not set
* sh-pfc Support for r8a73a4 SoC
* Move GPIOs handling from the PFC device to separate GPIO devices on the r8a7779 SoC

This pull request is based on a merge of:
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas renesas-pinmux-for-v3.10
git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas renesas-soc2-for-v3.10

This merge is made to supply run-time dependencies for the following
patches that will bea added on top:

ARM: shmobile: APE6EVM LAN9220 support
ARM: shmobile: APE6EVM PFC support
上级 ac22dde7 202ac6a2
