-* ARC EMAC 10/100 Ethernet platform driver for Rockchip RK3036/RK3066/RK3188 SoCs
-
-Required properties:
-- compatible: should be "rockchip,<name>-emac"
- "rockchip,rk3036-emac": found on RK3036 SoCs
- "rockchip,rk3066-emac": found on RK3066 SoCs
- "rockchip,rk3188-emac": found on RK3188 SoCs
-- reg: Address and length of the register set for the device
-- interrupts: Should contain the EMAC interrupts
-- rockchip,grf: phandle to the syscon grf used to control speed and mode
- for emac.
-- phy: see ethernet.txt file in the same directory.
-- phy-mode: see ethernet.txt file in the same directory.
-
-Optional properties:
-- phy-supply: phandle to a regulator if the PHY needs one
-
-Clock handling:
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names: Shall be "hclk" for the host clock needed to calculate and set
- polling period of EMAC and "macref" for the reference clock needed to transfer
- data to and from the phy.
-
-Child nodes of the driver are the individual PHY devices connected to the
-MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus.
-
-Examples:
-
-ethernet@10204000 {
- compatible = "rockchip,rk3188-emac";
- reg = <0xc0fc2000 0x3c>;
- interrupts = <6>;
- mac-address = [ 00 11 22 33 44 55 ];
-
- clocks = <&cru HCLK_EMAC>, <&cru SCLK_MAC>;
- clock-names = "hclk", "macref";
-
- pinctrl-names = "default";
- pinctrl-0 = <&emac_xfer>, <&emac_mdio>, <&phy_int>;
-
- rockchip,grf = <&grf>;
-
- phy = <&phy0>;
- phy-mode = "rmii";
- phy-supply = <&vcc_rmii>;
-
- #address-cells = <1>;
- #size-cells = <0>;
- phy0: ethernet-phy@0 {
- reg = <1>;
- };
-};
