Subject: [PATCH] MIPS: DTS: CI20: fix otg power gpio

According to schematics it is PF15 and not PF14 (MIC_SW_EN).
Seems as if it was hidden and not noticed during testing since
there is no sound DT node.

Fixes: 158c774d3c64 ("MIPS: Ingenic: Add missing nodes for Ingenic SoCs and boards.")

Looking at the schematics it looks like you are correct. So:
Acked-by: Paul Cercueil <[email protected]>

I'm curious though, it is connected to the "SYS_POWER_IND" trace in the
schematic, which seems to also switch the main led between red and
blue, is that the case?

Cheers,
-Paul

Thanks!

Yes, the LED changes between blue and red with this patch.

I missed it, but every time you have a Fixes: tag, you also need to add
below:
Cc: [email protected]

unless the bug you fix is in one of the RCs (and not in a released
kernel).

I think you should send a V2 with this tag (and my ACK).

Cheers,
-Paul

Ah, yes. I missed this too. Checkpatch could have warned but doesn't...

Will do asap.

I don't think you do any more. The stable team grabs anything that
looks even vaguely like a fix and applies it. Having a valid Fixes tag
is enough for the stable team to take interest.
