Mediatek Gigabit Switch
The mediatek gigabit switch can be found on Mediatek SoCs.
Required properties:
- compatible: Should be "mediatek,mt7620-gsw", "mediatek,mt7621-gsw",
- reg: Address and length of the register set for the device
- interrupts: Should contain the gigabit switches interrupt
Additional required properties for ARM based SoCs:
- mediatek,reset-pin: phandle describing the reset GPIO
- clocks: the clocks used by the switch
- clock-names: the names of the clocks listed in the clocks property
these should be "trgpll", "esw", "gp2", "gp1"
- mt7530-supply: the phandle of the regulator used to power the switch
- mediatek,pctl-regmap: phandle to the port control regmap. this is used to
setup the drive current
Optional properties:
- interrupt-parent: Should be the phandle for the interrupt controller
that services interrupts for this device
