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