GPU on A64 currently runs at default frequency, which is 297 MHz. This is a bit low in some cases and noticeable lag can be observed in GPU rendered UIs. GPU is capable to run at 432 MHz. Add GPU OPP table. Signed-off-by: Jernej Skrabec <jernej.skrabec@gmail.com> --- arch/arm64/boot/dts/allwinner/sun50i-a64.dtsi | 17 +++++++++++++++++ 1 file changed, 17 insertions(+)
