From: Rob Clark Date: Fri, 5 Sep 2014 17:30:27 +0000 (-0400) Subject: drm/msm/adreno: move decision about what gpu to to load X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e2550b7a7d8f2030cfea43343eb3fccc3a8e8167;p=linux-beck.git drm/msm/adreno: move decision about what gpu to to load Move this into into adreno_device, and decide based on gpu revision rather than just assuming a3xx.
