Subject: [PATCH] arm64: dts: rockchip: Add GPU OPP voltage ranges to RK356x
SoC dtsi
Add support for voltage ranges to the GPU OPPs defined in the SoC dtsi for
Rockchip RK356x. This is, for example, useful for RK356x-based boards that
are designed to use the same power supply for the GPU and NPU portions of
the SoC, which is described further in the following documents:
- Rockchip RK3566 Hardware Design Guide, version 1.1.0, page 37
- Rockchip RK3568 Hardware Design Guide, version 1.2, page 78
The values for the exact GPU OPP voltages and the lower limits for the GPU
OPP voltage ranges differ from the values found in the vendor kernel source
(cf. downstream commit f8b9431ee38e ("arm64: dts: rockchip: rk3568: support
adjust opp-table by otp")), [1][2] and present the exact GPU OPP voltage
values that have served us well so far.

Subject: [PATCH] arm64: dts: rockchip: Update GPU OPP voltages in RK356x SoC
dtsi
Update the values for the exact Rockchip RK356x GPU OPP voltages and the
lower limits for the GPU OPP voltage ranges, using the most conservative
values (i.e. the highest per-OPP voltages) found in the vendor kernel source
(cf. downstream commit f8b9431ee38e ("arm64: dts: rockchip: rk3568: support
adjust opp-table by otp")). [1][2]
Using the most conservative per-OPP voltages ensures reliable GPU operation
regardless of the actual GPU binning, with the downside of possibly using
a bit more power than absolutely needed.
