4 - compatible: should be one of the following:
5 "cdns,sd4hc" - default of the IP
6 "socionext,uniphier-sd4hc" - for Socionext UniPhier SoCs
7 - reg: offset and length of the register set for the device.

Dmmc.txt6 - reg: Registers location and length.
7 - interrupts: Interrupts used by the MMC controller.
12 - broken-cd: There is no card detection available; polling must be used.
13 - cd-gpios: Specify GPIOs for card detection, see gpio binding
14 - non-removable: non-removable slot (like eMMC); assume always present.
17 - bus-width: Number of data lines, can be <1>, <4>, or <8>. The default
19 - wp-gpios: Specify GPIOs for write protection, see gpio binding
20 - cd-inverted: when present, polarity on the CD line is inverted. See the note
22 - cd-debounce-delay-ms: Set delay time before detecting card after card insert interrupt.
23 It's only valid when cd-gpios is present.
