We just seem to have 3 uarts pinned out. so why alias the rest? those
seem unused?

bootph-all here?
Please check Documentation/devicetree/bindings/dts-coding-style.rst

1. "compatible"
2. "reg"
3. "ranges"
4. Standard/common properties (defined by common bindings, e.g. without
vendor-prefixes)

^^ bootph property last one here.

5. Vendor-specific properties
6. "status" (if applicable)
7. Child nodes, where each node is preceded with a blank line

Could you make sure that all the nodes follow the convention?

This should have been disabled at am62-main.dtsi level (like it was done
in j784s4) - lets fix that then apply the pb2 without these disabled
nodes.

I think the commit message says MSPM0L1105 ? is this in emulation mode?
if so, we should document this.

is this the same? MSPM0L1105 doing eeprom? if so, please document.

Can this operate in "otg" instead? maybe use a type-c dock?

is'nt this over https://www.beagleboard.org/boards/techlab or
https://www.beagleboard.org/boards/pocketbeagle-gamepup-cape or
https://github.com/mwelling/pocket-bob ?

I think it is better as an overlay? Let us not enable something that
will add power for no benefit :)
Further USB1.ID has options for PRU as well. Let the daughter overlay
deal with it.

On the flip side, we could work the other way - since majority of
daughter cards use USB host, it could be that the other overlays can
just disable usbss1 and usb1

Thoughts?
