Subject: [PATCH net-next 0/4] net: lan966x: hardcode port count

Don't rely on the device tree to count the number of physical port. Instead
introduce a new compatible string which the driver can use to select the
correct port count.

This also hardcodes the generic compatible string to 8. The rationale is
that this compatible string was just used for the LAN9668 for now and I'm
not even sure the current driver would support the LAN9662.

Michael Walle (4):
  net: lan966x: hardcode the number of external ports
  dt-bindings: net: lan966x: add specific compatible string
  net: lan966x: add new compatible microchip,lan9668-switch
  ARM: dts: lan966x: use new microchip,lan9668-switch compatible
