Hi,

(trying again in plaintext, sorry for the HTML spam...)

A bit tricky to reply to two mails in one, as I think my reply relates
to both, but here it goes.

That sounds sensible, I will do that in v3.

Agreed. But: I think the same goes for UARTs 0-3, of which 0-1 have a pinmux
following the _a / @0 syntax in current kernel. There are not really options
here, except leaving out RTS/CTS on uarts1-3, which one could do in a
board-specific pinmux.

Moreover, I could put all the pinmux-peripheral associations for H3 in the DTSI,
removing them from the DTS files (including already existing), as the
associations themselves are not really board specific, right?

Best,
Jorik
