Hi,
This series first adds device nodes for USB0_PHY_CTRL and USB1_PHY_CTRL
in the wkup_conf node and fixus up the USB nodes to use the newly
added nodes.
Then it adds USB support for AM62P5-SK board.
cheers,
-roger

Exposing the entire CTRL_MMR space to syscon is not a good idea.
Add sub-nodes for USB0_PHY_CTRL and USB1_PHY_CTRL and use them
in the USB0/USB1 nodes.

You'll want to add a binding for this to the simple syscon list.
See this patch for an example[0]. Otherwise this gives a DT check
warning.
Also, adding the new nodes for AM62p should be moved to the
next patch in this series. Fixing AM62 and AM62a should be
a standalone patch.

You'll want to add a binding for this to the simple syscon list.
See this patch for an example[0]. Otherwise this gives a DT check
warning.
Also, adding the new nodes for AM62p should be moved to the
next patch in this series. Fixing AM62 and AM62a should be
a standalone patch.

Not allowed alone and should cause warnings.
It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).
