  35                 "renesas,rcar-gen2-sdhi" - a generic R-Car Gen2 and RZ/G1 SDHI

  37                 "renesas,rcar-gen3-sdhi" - a generic R-Car Gen3 or RZ/G2
  38                                            SDHI controller
  39
  40
  41                 When compatible with the generic version, nodes must list
  42                 the SoC-specific version corresponding to the platform
  43                 first followed by the generic version.
  44
  45 - clocks: Most controllers only have 1 clock source per channel. However, on
  46           some variations of this controller, the internal card detection
  47           logic that exists in this controller is sectioned off to be run by a
  48           separate second clock source to allow the main core clock to be turned
  49           off to save power.
  50           If 2 clocks are specified by the hardware, you must name them as
  51           "core" and "cd". If the controller only has 1 clock, naming is not
  52           required.
  53           Devices which have more than 1 clock are listed below:
  54           2: R7S72100, R7S9210
  55
  56 Optional properties:
  57 - pinctrl-names: should be "default", "state_uhs"
  58 - pinctrl-0: should contain default/high speed pin ctrl
  59 - pinctrl-1: should contain uhs mode pin ctrl
