The second patch updates the values for the exact GPU OPP voltages and the lower limits for the GPU OPP voltage ranges, so they match the most conservative values (i.e. the highest per-OPP voltages) found in the vendor kernel source. This is performed in a separate patch to allow easier regression tracking, in the unlikely case that some issues are discovered later, resulting from these voltage changes. Changes in v3: - Turned into a patch series by adding a second patch that updates the exact GPU OPP voltages and the lower limits for the GPU OPP voltage ranges so they match the most conservative values found in the vendor kernel source [1] Changes in v2: - Dropped support for optional GPU OPP voltage ranges, which may actually hide some misconfiguration issues in board dts files, [2] but that will be covered by other debugging patches [3] Link to v2: https://lore.kernel.org/linux-rockchip/bdb60f1f793166cd65f58ab7aea025347076019c.1719679068.git.dsimic@manjaro.org/T/#u Link to v1: https://lore.kernel.org/linux-rockchip/446399362bd2dbeeaecd8351f68811165429749a.1719637113.git.dsimic@manjaro.org/T/#u [1] https://lore.kernel.org/linux-rockchip/b8951ac4e29184fa35919c6ab85b8f87@manjaro.org/ [2] https://lore.kernel.org/linux-rockchip/f10d5a3c425c2c4312512c20bd35073c@manjaro.org/ [3] https://lore.kernel.org/linux-rockchip/36170f8485293b336106e92346478daa@manjaro.org/ Dragan Simic (2): arm64: dts: rockchip: Add GPU OPP voltage ranges to RK356x SoC dtsi arm64: dts: rockchip: Update GPU OPP voltages in RK356x SoC dtsi arch/arm64/boot/dts/rockchip/rk356x.dtsi | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-)
