Refer to mmc.txt for standard MMC bindings.
+For UHS devices which require tuning, the device tree should have a "cpu_thermal" node which maps to the appropriate thermal zone. This is used to get the temperature of the zone during tuning.

Required properties:
- compatible: Should be "ti,dra7-sdhci" for DRA7 and DRA72 controllers
Should be "ti,k2g-sdhci" for K2G
