+Optional properties:
- clock-names: Should contain "emmcclk". Although this is listed as optional
(because most boards can get basic functionality without having
access to it), it is strongly suggested.
+ See ../clock/clock-bindings.txt for details.
- clocks: Should have a phandle to the card clock exported by the SDHCI driver.
+ - drive-impedance-ohm: Specifies the drive impedance in Ohm.
+ Possible values are 33, 40, 50, 66 and 100.
+ If not set, the default value of 50 will be applied.
