From: Patrik Jakobsson Date: Wed, 14 Aug 2013 22:54:44 +0000 (+0200) Subject: drm/gma500/cdv: Add and hook up chip op for disabling sr X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=75346fe9bc4c9b366c760200a665a2c55b789389;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/gma500/cdv: Add and hook up chip op for disabling sr Add a callback hook to the chip ops struct to allow chips to have their specific self-refresh function. Currently only used by cdv.
