[PATCH v3] ARM: OMAP1: Prepare for conversion of OMAP1 clocks to CCF

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In preparation for conversion of OMAP1 clocks to common clock framework,
identify arch/arm/mach-omap1 local users of those clocks and update them
to call clk_prepare_enable/clk_disable_unprepare() instead of just
clk_enable/disable(), as required by CCF implementation of clock API.

Users which reside under /drivers will be updated via separate patches,
split out from v2 and already submitted.
