AM62P supports image capture via the MIPI CSI-2 protocol, it uses three
IPs to achieve this: Cadence DPHY, Cadence CSI-RX, and TI's pixelgrabber
wrapper on top. Enable all of these IPs in the devicetree.


Add nodes and keep them disabled sounds more apt here as you are keeping all of these disabled.
