You could Not all drivers have handle power domains and clocks appropriately, It may triggers bugs, but since it's a V4l2 driver not DRM driver, i will enable it for all rk3288 boards.

To keep consistent, i didn't enable it in .dtsi. >> >> 6 files changed, 24 insertions(+) > > -- > Regards, > > Laurent Pinchart >
