| 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. | ||
