Hi Krzysztof,
Thanks for the review.
I picked that based on the last 20-30 commits under
arch/arm64/boot/dts/. Would you prefer something starting "arm64: dts:
freescale: "? I see that "arm64: dts: imx8mp: " is typically being used
for changes to the more generic imx8mp device trees...

I note that the device binding file lists an example using
"extcon_usb1". I also note that existing users seem to broadly use a
variation of "extcon-XXXX", would "extcon-usb0" be acceptable in this
case?

My apologies - I thought I'd got all of these...

No, despite having written device tree bindings on and off for
something approaching 18 years (though admittedly more off than on), I
was unaware of this tool. I'll run this before resubmitting.

Sorry - I missed that one. I'd moved most of the compatible strings to
the top of nodes.
