Sorry I missed this warning from v7.

This patch depends on 9536cc949235 ("media: dt-bindings: cadence-csi2rx: 
Convert to DT schema") which is part of linux-next.

The base for this series should be linux-next/master 
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git 
instead of 6.5-rc1.
