From a7fe3a845049b62275ab660b51b6bc1300177d22 Mon Sep 17 00:00:00 2001 From: seshendra Gadagottu Date: Tue, 23 Jan 2018 10:01:45 -0800 Subject: gpu: nvgpu: gv11b: enable devfreq After moving devfreq enable to end of finalize power on, intermittent issues related to gpu booting with devfreq enabled are fixed. Enabled devfreq for gv11b by enabling ""nvhost_podgov" governor in platform data. Reused scaling functions from gp10b/gk20a. Removed emc floor on railgate for power saving. Added max emc frequency as floor in rail-ungate for faster gpu boot.
