SDHI controller
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
Example: R8A7790 (R-Car H2) SDHI controller nodes
