42		When compatible with the generic version, nodes must list
43		the SoC-specific version corresponding to the platform
44		first followed by the generic version.
45
46- clocks: Most controllers only have 1 clock source per channel. However, on
47	  some variations of this controller, the internal card detection
48	  logic that exists in this controller is sectioned off to be run by a
49	  separate second clock source to allow the main core clock to be turned
50	  off to save power.
51	  If 2 clocks are specified by the hardware, you must name them as
52	  "core" and "cd". If the controller only has 1 clock, naming is not
53	  required.
54	  Devices which have more than 1 clock are listed below:
55	  2: R7S72100, R7S9210
56
57Optional properties:
58- pinctrl-names: should be "default", "state_uhs"
59- pinctrl-0: should contain default/high speed pin ctrl
60- pinctrl-1: should contain uhs mode pin ctrl
