Subject: [PATCH] drm/msm/a6xx: Add support for Adreno 612
From: Jie Zhang <quic_jiezh@...cinc.com>
Add support for Adreno 612 GPU found in SM6150/QCS615 chipsets.
A612 falls under ADRENO_6XX_GEN1 family and is a cut down version
of A615 GPU.
A612 has a new IP called Reduced Graphics Management Unit or RGMU
which is a small state machine which helps to toggle GX GDSC
(connected to CX rail) to implement IFPC feature. It doesn't support
any other features of a full fledged GMU like clock control, resource
voting to rpmh etc. So we need linux clock driver support like other
gmu-wrapper implementations to control gpu core clock and gpu GX gdsc.
Since there is no benefit with enabling RGMU at the moment, RGMU is
entirely skipped in this patch.

Mesa support is already available for A612. Verified Glmark2 with
weston.
Some dependencies for the devicetree change are not yet available
in the mailing lists. I will send it out as a separate patch later.
