Just following what previous commits did. :) > Reviewed-by: Jagan Teki <jagan@amarulasolutions.com> BTW, I know you've been trying to get CSI to work on the A64. I have it working for the Bananapi-M64. The CSI SCLK needs to be lowered to 300 MHz or the image gets corrupted. ChenYu

I'd drop the latter, but perhaps elaborate a bit this is about CSI. Fine details... I think it's fine as-is for now. > > > Reviewed-by: Jagan Teki <jagan@amarulasolutions.com> > > BTW, I know you've been trying to get CSI to work on the A64. > I have it working for the Bananapi-M64.

The CSI controller found on the H3 (and H5) is a reduced version of the one found on the A31. It only has 1 channel, instead of 4 channels for time-multiplexed BT.656. Since the H3 is a reduced version, it cannot "fallback" to a compatible that implements more features than it supports. Split out the H3 compatible as a separate entry, with no fallback.
