The reset which is used by the switch to reset the switch core has many
different side effects. It is not just a switch reset. Thus don't treat it
as one, but just issue the reset early during boot.

Michael Walle (3):
  reset: microchip-sparx5: issue a reset on startup
  dt-bindings: net: sparx5: don't require a reset line
  net: lan966x: make reset optional

Philipp, you could just patch #1, I guess. I'd then
resend patches #2 and #3 to the netdev ML targetting net-next.
As long as the device tree itself isn't changed, there should
be no dependency between these two.
