  sh-pfc: r8a7779: Don't group USB OVC and PENC pins (2013-05-22 22:01:59 +0900)

----------------------------------------------------------------
Correction to USB OVC and PENC pin groupings on r8a7779 SoC.
This avoids conflicts when the USB_OVCn pins are used by another function.
This has been observed to be a problem in v3.10-rc1.

[PATCH] libata: do not limit R-Car SATA driver to shmobile

The motivation for this is to allow the driver to be
used with the r8a7790 SoC.

I believe that rather than adding another SoC to the list of allowed SoCs
it is better to simply remove the dependency of the driver on shmobile all
together.

[Announce] Renesas branches rebased on v3.10-rc2

Hi,

I have rebased all branches of the renesas tree that are targeted
at v3.11 on top of v3.10-rc2. I have also merged these into
a new next branch which I have pushed and tagged as renesas-next-20130523.
This should appear in linux-next in the not to distant future.

There are a few -fixes branches which resolve problems in v3.10-rc1. I will
get pull requests to arm-soc for those branches in the not to distant
future. The target for -fixes branches is v3.10.

As this took a while I am a little behind with picking up patches that
have been posted, but I hope to catch up over the next few days.

Moving forwards, assuming that nothing dramatic happens I will start
sending pull requests to arm-soc for the non-fixes branches so they
can be included in v3.11. At this stage I plan to start doing that
next week.

Known problems: Booting marzen-reference seems flakey and I'm entirely
unsure why.

[PATCH 1/2] ARM: shmobile: sh73a0: do not overwrite all div4 clock operations

An earlier commit "ARM: shmobile: sh73a0: add support for adjusting CPU
frequency" intended to replace some clock operations only for the Z-clock,
instead it replaced them for all div4 clocks, since all div4 clocks share
the same copy of clock operations. Fix this by using a separate clock
operations structure for Z-clock.
