[PATCH v2 0/5] Add HUSB311 Type-C controller

[Alexey Charkov]

HUSB311 is a drop-in replacement for RT1711H, used in Rockchip RK3576 EVB1
board and some other boards closely following the reference schematic.

The existing RT1711H driver seems to work fine with HUSB311, and publicly
available documentation does not provide enough information for HUSB311 
to identify any meaningful differences, so this series wires up the
existing driver to treat HUSB311 in the same way it treats RT1711H, by the
way of introducing fallback compatibles in the binding and removing
unnecessary VID/PID/DID checks from the driver.

Note that patches 2 and 4 are on top of commits by Yanshen Cao which are
currently in next but not in master. Maybe they can be squashed in full
or in part to reduce churn, if we agree on using fallback compatibles.
>From what I can tell, ET7304 can also be used with a fallback compatible
alone and without driver changes once VID/PID/DID checks are removed (I
don't see it used in any DTS in either mainline or next yet, though)

This also enables a bare-bones DT node for HUSB311 on RK3576 EVB1, but
currently misses the connections graph for the USB SS and SBU lines, as
those might require the USBDP PHY ports schema to be updated first for
proper DP AltMode support as indicated by Sebastian.

Changes in v2:
- Changed the binding to use fallback compatibles (thanks Conor for the suggestion)
- Rebased on top of recent next, thus also adjusted the binding for ET7304 to fall
  back to RT1715. There are no in-tree DT users yet
- Removed the VID/PID/DID checks altogether instead of endlessly multiplying the
  list of matches for new clones (thanks Conor for the suggestion)
- Link to v1: https://lore.kernel.org/r/20260311-husb311-v1-0-f25bcb58cff7@flipper.net
