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.
