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
+ Should be "ti,am335-sdhci" for am335x controllers
+ Should be "ti,am437-sdhci" for am437x controllers
- ti,hwmods: Must be "mmc<n>", <n> is controller instance starting 1
(Not required for K2G).
- pinctrl-names: Should be subset of "default", "hs", "sdr12", "sdr25", "sdr50",
