From: Rodrigo Vivi Date: Thu, 6 Jul 2017 20:41:13 +0000 (-0700) Subject: drm/i915/cnl: Inherit RPS stuff from previous platforms. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=35ceabf3cdb557b23bbc09f0b6f7bb2b545185b1;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915/cnl: Inherit RPS stuff from previous platforms. Apparently no change on RPS stuff from previous platforms. v2: Merging to rps related patches in one and also adding missed cases.
