Based on linux-gpio discussion [1], it is best practice to make the
gpio-line-names unique. Generic names like "[ethernet]" are replaced
with the name of the unique signal on the AM3358 SoC ball corresponding
to the gpio line. "[NC]" is also renamed to the standard "NC" name to
represent "not connected".

So are these needed for v5.12 as fixes, or can these wait until after
the merge window for v5.13?

I suppose it depends on if/when the patches to make gpio lines unique
go in. I believe the last response from Linus W. was in mid-December
and indicated he holding off merging as it was immature [1]

Thanks,

There is no hurry with that plus I hold that patch back indefinately
as it seems. I want to make line names unique for devices not
probing from DT but DT devices, I dunno.

Applying this one into omap-for-v5.13/dt thanks. However the second patch
does not apply against v5.12-rc2, Drew can you please repost the second
patch?

Hi Tony, I have posted a new patch that applies okay to mainline.
