[PATCH 5/5] drm/msm/A6x: Add devfreq support in A6x

2018-08-23 Thread Sharat Masetty
Implement routines to estimate GPU busy time and fetching the current frequency for the polling interval. This is required by the devfreq framework which recommends a frequency change if needed. The driver code then tries to set this new frequency on the GPU by sending an Out Of Band(OOB) request.
