Set VPU G2 clock to 300MHz like described in documentation.
This fix pixels error occurring with large resolution ( >= 2560x1600)
HEVC test stream when using the postprocessor to produce NV12.
Fixes: 4ac7e4a81272 ("arm64: dts: imx8mq: Enable both G1 and G2 VPU's with vpu-blk-ctrl")

I assume you are suggesting s/fix/fixes? I can fix it up when applying.
Thanks!

We use prefix "arm64: dts: ..." for arm64 DTS changes. I fixed it up
and applied the patch.
