[PATCH 0/6] v3u: add & update (H)SCIF nodes

[PATCH 0/6] v3u: add & update (H)SCIF nodes

[Wolfram Sang]

SCIF0 already worked because of firmware settings, but let's have a
proper node for it. Also add HSCIF0 because the last patch shows that it
also works. Because these blocks work in general, let's add the other
instances to the DTSI, too.

These additions make me a bit wonder about the 'reg'-based sorting in
our DTSI files. It looks a bit messy to me, but I kept it for
consistency. Same with the (H)SCIF reg sizes which are a tad too large
but in sync with our other DTSI files.

Looking forward to comments!

All the best,

   Wolfram

Can we apply this via the serial tree? Or shall we take it via
renesas-soc? Thanks!

I can take it, but normally I try to wait for a DT maintainer ack.

If you want to take it, feel free to as well.

thanks,
