[PATCH 4/4] drm/msm/adreno: add support for a730
Jonathan Marek
jonathan at marek.ca
Sun Mar 27 20:25:57 UTC 2022
Based on a6xx_gpu.c, stripped down and updated for a7xx based on the
downstream driver. Implements the minimum to be able to submit commands to
the GPU and use it for userspace driver development. Notably this doesn't
implement support for the GMU (this means that the clock driver needs to
support the GPU core clock and turning on the GX rail, which is normally
offloaded to the GMU).
