From: Joonyoung Shim Date: Wed, 27 Jun 2012 05:27:09 +0000 (+0900) Subject: drm/exynos: add plane enable/disable X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cf5188ac1c0726a6bd2565734ec080f0eca82736;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/exynos: add plane enable/disable The plane enable/disable can control only a power of plane, so they will be helpful to handle planes with dpms.
