Subject: arm: keystone: remove boilerplate code and use USE_PM_CLK_RUNTIME_OPS
X-Git-Tag: v4.14-rc1~5225^2~4^2~5
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1f51b0c6461eb72595c2b69b79ca69a322ed1d0e;p=platform%2Fkernel%2Flinux-rpi.git

arm: keystone: remove boilerplate code and use USE_PM_CLK_RUNTIME_OPS

USE_PM_CLK_RUNTIME_OPS is introduced so we don't repeat the same code
to do runtime_suspend and runtime_resume across users of PM clocks.
Use it to remove the boilerplate code.
