| - compatible: rockchip,rk3399-emmc-phy |
| - reg: PHY register address offset and length in "general |
| - clock-names: Should contain "emmcclk". Although this is listed as optional |
| (because most boards can get basic functionality without having |
| access to it), it is strongly suggested. |
| See ../clock/clock-bindings.txt for details. |
| - clocks: Should have a phandle to the card clock exported by the SDHCI driver. |
| - drive-impedance-ohm: Specifies the drive impedance in Ohm. |
| Possible values are 33, 40, 50, 66 and 100. |
| If not set, the default value of 50 will be applied. |
| - rockchip,enable-strobe-pulldown: Enable internal pull-down for the strobe |
| line. If not set, pull-down is not used. |
| - rockchip,output-tapdelay-select: Specifies the phyctrl_otapdlysec register. |
| If not set, the register defaults to 0x4. |
