7Required properties:
8
9- compatible: should be "renesas,mmcif-<soctype>", "renesas,sh-mmcif" as a
10  fallback. Examples with <soctype> are:
11	- "renesas,mmcif-r8a7740" for the MMCIF found in r8a7740 SoCs
12	- "renesas,mmcif-r8a7790" for the MMCIF found in r8a7790 SoCs
13	- "renesas,mmcif-r8a7791" for the MMCIF found in r8a7791 SoCs
14	- "renesas,mmcif-r8a7794" for the MMCIF found in r8a7794 SoCs
15
16- clocks: reference to the functional clock
17
18- dmas: reference to the DMA channels, one per channel name listed in the
19  dma-names property.
20- dma-names: must contain "tx" for the transmit DMA channel and "rx" for the
21  receive DMA channel.
22- max-frequency: Maximum operating clock frequency, driver uses default clock
23  frequency if it is not set.
