Beacon Embedded has an i.MX8M Plus development kit which consists
of a SOM + baseboard. The SOM includes Bluetooth, WiFi, QSPI, eMMC,
and one Ethernet PHY. The baseboard includes audio, HDMI, USB-C Dual
Role port, USB Hub with five ports, a PCIe slot, and a second Ethernet
PHY.

No improvements ... I'll stop reviewing. No point if you do not intend

The lack of makefile was an honest mistake as I forgot to add it to my
patch. I ran the make dt_binding_check and addressed many of the
errors, but some of them are not unique to my board, because they were
errors in the imx8mp.dtsi file. I addressed some of them by sending
patches to fix some types in imx8mp.dtsi. I will make sure V3 has the
makefile updated.

I forgot the git commit --amend so my patch was missing the changes,
but my machine has the fix. Sorry about that.

I am not sure what I am supposed to do here. I already have one node
called "gpio@20" and as far as I know, I can't have duplicate nodes
with the same name. I have the same GPIO expander with the same on a
different i2c bus. Do you have a recommendation as to what name I
should use so the names are unique?

I changed this node from tcpc to ptn5110 per your last comment, and it
matches other boards that use this and
Documentation/devicetree/bindings/connector/usb-connector.yaml example
uses ptn5110.
Documentation/devicetree/bindings/usb/typec-tcpci.txt just called it
"ptn5110@50" .
imx8mm-evk.dtsi calls it "ptn5110: tcpc@50" so that's the example I
followed. I am guessing it fails the build test because there isn't a
yaml file for this driver.
I wasn't intentionally ignoring your comments, and I honestly tried to
catch them.
If you let me know how you want me to proceed, I will do a V3.

My comment was that node name has to be generic. ptn5110 is not generic
but specific. I gave you reference to examples of generic names but in
other boards there are more examples how this could be named.

I stopped reviewing. Implement all the comments but if something is not
clear, just ask for clarification.
