MediaTek SGMIISYS controller
============================
The MediaTek SGMIISYS controller provides various clocks to the system.
Required Properties:
- compatible: Should be:
- "mediatek,mt7622-sgmiisys", "syscon"
- "mediatek,mt7629-sgmiisys", "syscon"
- #clock-cells: Must be 1
- mediatek,physpeed: Should be one of "auto", "1000" or "2500" to match up
the capability of the target PHY.
The SGMIISYS controller uses the common clk binding from
Documentation/devicetree/bindings/clock/clock-bindings.txt
The available clocks are defined in dt-bindings/clock/mt*-clk.h.
Example:
sgmiisys: sgmiisys@1b128000 {
compatible = "mediatek,mt7622-sgmiisys", "syscon";
reg = <0 0x1b128000 0 0x1000>;
#clock-cells = <1>;
};
