-Mediatek Gigabit Switch
-=======================
-
-The mediatek gigabit switch can be found on Mediatek SoCs.
-
-Required properties:
-- compatible: Should be "mediatek,mt7620-gsw", "mediatek,mt7621-gsw",
- "mediatek,mt7623-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
-
-Example:
-
-gsw: switch@1b100000 {
- compatible = "mediatek,mt7623-gsw";
- reg = <0 0x1b110000 0 0x300000>;
-
- interrupt-parent = <&pio>;
- interrupts = <168 IRQ_TYPE_EDGE_RISING>;
-
- clocks = <&apmixedsys CLK_APMIXED_TRGPLL>,

- <&ethsys CLK_ETHSYS_GP2>,
- <&ethsys CLK_ETHSYS_GP1>;
- clock-names = "trgpll", "esw", "gp2", "gp1";

-- verify devicetree documentation is consistent with code
-- fix ethtool - currently doesn't return valid data.
-- general code review and clean up
-- add support for second MAC on mt7621
-- convert gsw code to use switchdev interfaces
-- md7620_mmi_write etc should probably be wrapped
- in a regmap abstraction.
-- Get soc_mt7621 to work with QDMA TX if possible.
-- Ensure phys are correctly configured when a cable
- is plugged in.
