Subject[PATCH 00/12] Prepare various SH/R Mobile/Car drivers for CCF migration
Date
Hello,

This patch series, based on v3.12-rc7, prepares various Renesas SH-Mobile,
R-Mobile and R-Car drivers for migration to CCF by adding clock prepare and
unprepare support.

The patches are pretty straightforward. Most of the drivers called
clk_enable and clk_disable in sleepable context, I've thus just converted them
to clk_prepare_enable and clk_disable_unprepare.

The clocksource drivers were slightly more complex to handle as clk_enable and
clk_disable were called in non-sleepable context. As the clocksource framework
architecture doesn't provide any sleepable callback in which clocks could be
prepared and unprepared, I've added clk_prepare and clk_unprepare calls in the
probe and suspend/resume handlers (clocksources can't be removed so the remove
handler doesn't need a clk_unprepare call).

I'd like to get all these patches merged in v3.14. As they will need to go
through their respective subsystems' trees, I would appreciate if all
maintainers involved could notify me when they merge patches from this series
in their tree to help me tracking the merge status. I don't plan to send pull
requests individually for these patches, and I will repost patches
individually if changes are requested during review.
