The patch here for sa8540p-ride already includes the drive strength. I
did pull this on top of usb-next and it is working well for me in a
quick sanity test. Konrad's pinctrl-names/pinctrl-0 swap is purely
cosmetic of course, but for what is worth that works fine too.
I'd add my Tested-by for this patch, but it seems silly since I authored
the original :)
Also, make CHECK_DTBS=y qcom/sa8540p-ride.dtb is still reporting issues,
but other reviewers have highlighted that I believe. Just for the record
though, make sure you get those silenced!
I look forward to the next revision.
Thanks,
Andrew
