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>,
|
|
||||||
<ðsys CLK_ETHSYS_ESW>,
|
|
||||||
<ðsys CLK_ETHSYS_GP2>,
|
|
||||||
<ðsys CLK_ETHSYS_GP1>;
|
|
||||||
clock-names = "trgpll", "esw", "gp2", "gp1";
|
|
||||||
|
|
||||||
mt7530-supply = <&mt6323_vpa_reg>;
|
|
||||||
|
|
||||||
mediatek,pctl-regmap = <&syscfg_pctl_a>;
|
|
||||||
mediatek,reset-pin = <&pio 15 0>;
|
|
||||||
|
|
||||||
status = "okay";

|
||||||

- 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.
