From: Rob Clark Date: Wed, 3 May 2017 14:43:14 +0000 (-0400) Subject: drm/msm/gpu: check legacy clk names in get_clocks() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=134ccada7ac59156761ce05afd1c0b1d02ebd928;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/msm/gpu: check legacy clk names in get_clocks() Otherwise if someone was using old bindings with "core_clk" instead of "core" as the clock name, we'd never find it and gpu would be stuck at 27MHz (or whatever it's slowest rate is).
