1Rockchip EMMC PHY 2----------------------- 3 4Required properties: 5 - compatible: rockchip,rk3399-emmc-phy 6 - #phy-cells: must be 0 7 - reg: PHY register address offset and length in "general 8 register files" 9 10Optional clocks using the clock bindings (see ../clock/clock-bindings.txt), 11specified by name: 12 - clock-names: Should contain "emmcclk". Although this is listed as optional 13 (because most boards can get basic functionality without having 14 access to it), it is strongly suggested. 15 - clocks: Should have a phandle to the card clock exported by the SDHCI driver. 16 17Example: 18 19 20grf: syscon@ff770000 { 21 compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd"; 22 #address-cells = <1>; 23 #size-cells = <1>; 24 25... 26 27 emmcphy: phy@f780 { 28 compatible = "rockchip,rk3399-emmc-phy"; 29 reg = <0xf780 0x20>; 30 clocks = <&sdhci>; 31 clock-names = "emmcclk"; 32 #phy-cells = <0>; 33 }; 34}; 35
