Document USB2 PHY for STM32MP25 USB2 controllers, which includes the
USB2.0 host-only controller and USB 2.0 part of the DWC3 controller.
Two such PHYs in total are present in STM32MP25 SoC, they both are
slightly different, therefore they use different compatible string

What is slightly different? This should be either here, or better, in
"description" part.

They are both Synopsys FEMTO-PHY , but they are each attached to a different controller (one to USB 2.0 host , the other to DWC3 DRD) , and their control bits in the system controller register are different for each variant.

I extended the description in V2.

to discern them.

Incomplete/incorrect DCO chain. Who sends it? Rahul?
This is lifted from the ST downstream kernel fork, it's a combination of a bunch of commits there and then cleaned up. Pankaj and Fabrice did most of the downstream work, I did the clean up for upstreaming. I collected the SoB lines from all the commits from ST downstream fork and added mine, hence this list. How shall I address this correctly, with some Co-developed-by tag ? Who gets which tag ?

additionalProperties is addressed in V2, so is the reported from Rob's bot regarding the botched compatible string in example.

Thanks !
