From d71d38087ded679f60714dae3a859523a19df04f Mon Sep 17 00:00:00 2001 From: Terje Bergstrom Date: Thu, 24 May 2018 15:25:41 -0700 Subject: gpu: nvgpu: Separate timer from bus Code touching timer registers was combined with bus code. They're two logically separate register spaces, so separate the code accordingly.
