Hi Amin, Thanks for the patch, LGTM! On 9/25/26 14:16, Amin Gattout wrote:
Add a device tree overlay for the Radxa Camera 4K (featuring the Sony IMX415 image sensor) to be applied on the Radxa ROCK 4D camera connector. The camera connects to CSI HOST1 through the MIPI D-PHY0 in full mode. Signed-off-by: Amin Gattout <redacted>
