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.

20grf: syscon@ff770000 {
21 compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";
22 #address-cells = <1>;
23 #size-cells = <1>;

30 clocks = <&sdhci>;
31 clock-names = "emmcclk";
32 #phy-cells = <0>;
