Properties "compatible", "clocks" and "clock-names" are documented.
Properties "bus-width", "cd-gpios" and "wp-gpios" are documented in
mmc.txt as I described before the example. Should I describe them again?
Do I need to document common properties like "pinctrl-names",
"pinctrl-0", "reg" and "interrupts"?
