X-Git-Tag: v3.8~286^2~82
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=93d78394ac5ec72315e7f9a7193c6649d817a9eb;p=platform%2Fkernel%2Flinux-amlogic.git

rtc: rtc-spear: Add clk_{un}prepare() support

clk_{un}prepare is mandatory for platforms using common clock framework.
Because for SPEAr we don't do anything in clk_{un}prepare() calls, just
call them once in probe/remove.
