* Universal Flash Storage (UFS) Host Controller
UFSHC nodes are defined to describe on-chip UFS host controllers.
Each UFS controller instance should have its own node.
Required properties:
- compatible : compatible list, contains "jedec,ufs-1.1"
- interrupts : <interrupt mapping for UFS host controller IRQ>
- reg : <registers mapping>
Example:
ufshc@0xfc598000 {
compatible = "jedec,ufs-1.1";
reg = <0xfc598000 0x800>;
interrupts = <0 28 0>;
};
