I'll let Maxime or Chen-Yu tell you what they want but I think we could
have two different commits, one for AXP803 and one for AXP813. I don't
think we care about having one commit per added resource for the axp803
though.

You're not using it in this patch, please keep this change in the commit
where its use is introduced.

Thanks,
