1* ARC EMAC 10/100 Ethernet platform driver for Rockchip RK3036/RK3066/RK3188 SoCs 2 3Required properties: 4- compatible: should be "rockchip,<name>-emac" 5 "rockchip,rk3036-emac": found on RK3036 SoCs 6 "rockchip,rk3066-emac": found on RK3066 SoCs 7 "rockchip,rk3188-emac": found on RK3188 SoCs 8- reg: Address and length of the register set for the device 9- interrupts: Should contain the EMAC interrupts 10- rockchip,grf: phandle to the syscon grf used to control speed and mode 11 for emac. 12- phy: see ethernet.txt file in the same directory. 13- phy-mode: see ethernet.txt file in the same directory. 14 15Optional properties: 16- phy-supply: phandle to a regulator if the PHY needs one 17 18Clock handling: 19- clocks: Must contain an entry for each entry in clock-names. 20- clock-names: Shall be "hclk" for the host clock needed to calculate and set 21 polling period of EMAC and "macref" for the reference clock needed to transfer 22 data to and from the phy. 23 24Child nodes of the driver are the individual PHY devices connected to the 25MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus. 26 27Examples: 28 29ethernet@10204000 { 30 compatible = "rockchip,rk3188-emac"; 31 reg = <0xc0fc2000 0x3c>; 32 interrupts = <6>; 33 mac-address = [ 00 11 22 33 44 55 ]; 34 35 clocks = <&cru HCLK_EMAC>, <&cru SCLK_MAC>; 36 clock-names = "hclk", "macref"; 37 38 pinctrl-names = "default"; 39 pinctrl-0 = <&emac_xfer>, <&emac_mdio>, <&phy_int>; 40 41 rockchip,grf = <&grf>; 42 43 phy = <&phy0>; 44 phy-mode = "rmii"; 45 phy-supply = <&vcc_rmii>; 46 47 #address-cells = <1>; 48 #size-cells = <0>; 49 phy0: ethernet-phy@0 { 50 reg = <1>; 51 }; 52}; 53
