Subject[PATCH v2 4/5] arm64: dts: qcom: sm8150: Add GPU speedbin support
Date
SM8150 has (at least) two GPU speed bins. With the support added on the
driver side, wire up bin detection in the DTS to restrict lower-quality
SKUs from running at frequencies they were not validated at.

Tested-by: Marijn Suijten <marijn.suijten@somainline.org> # On Sony Xperia 5 (speed bin 0x3)
Reviewed-by: Marijn Suijten <marijn.suijten@somainline.org>
