[PATCH net-next v4 00/13] macb usrio/tsu patches

[Conor Dooley]

From: Conor Dooley <conor.dooley at microchip.com>

Hey folks,

At the very least, it'd be good of the soc vendor folks could check
their platforms and see if their usrio stuff actually lines up with what
the driver currently calls "macb_default_usrio". Ours didn't and it was
a nasty surprise.

Ryan and I figured out that the sama7g5 stuff is not actually using the
same usrio bits as earlier devices, so there's now more patches in this
series to split them apart. I've not tested the split or the new
property due to lack of hardware, but Ryan has.

Marking this stuff net-next, because although they're fixes I don't see
any particular urgency, and it avoids creating some dependencies between
cleanup items and the fixes.

Cheers,
Conor.

v4:
- deprecate instead of remove existing devicetree property
- pick up Theo's patches

v3:
- reorder patches
- fix smatch issue reported by Simon
- add patches reworking usrio handling of clken/refclk (and remove the
  issue the llm reported in the process)
- add a new devicetree property for refclk selection, replacing the
  existing one.
- drop the dts patch
