Does this also include J722s data? I prefer if we could introduce both
SoC support together as one is superset of the other. Vaishav?

This did not include J722S data and also CSI2RX data for both devices, I have
added those and sent a V2 for this patch:

I prefer separate patches for udma and psil, please.
The patch on top of adding the PSIL map, it also adds support for am62P
in the UDMA driver.
