I don't have pending changes for this file for this kernel release. As
your series contains DT changes, I'm fine if this patch gets merged
through the ARM SoC tree along with the rest. Otherwise please let me
know if I should handle it myself.

Thank you Laurent, I think this patch can go along with the rest, if that's OK with
Simon?

Is that the correct one ? I don't see how CAN support is related.

Is the label physically present on the device (printed on the board or
the case) ?

Apart from that, without access to the schematics I can't really tell if
the DT is correct, but nothing strikes me as really wrong, so

I didn't know you had no access to the schematics, on their way...

Thank you. I confirm the DT looks good.

On a side note, there's an ESD protection and level shifter chip between
the HDMI output and the HDMI connector. On this board all its control
pins are hardwired to fixed levels, so it's completely transparent, but
in other cases it should be modelled in DT. I'm working on a driver for
the TPD12S015 which should be quite similar, I will post it soon.
