* Universal Flash Storage (UFS) DesignWare Host Controller



DWC_UFS nodes are defined to describe on-chip UFS host controllers and MPHY.

Each UFS controller instance should have its own node.



Required properties:

- compatible	: compatible list must contain the PHY type & version:

			"snps,g210-tc-6.00-20bit"

			"snps,g210-tc-6.00-40bit"

		  complemented with the Controller IP version:

			"snps,dwc-ufshcd-1.40a"

		  complemented with the JEDEC version:

			"jedec,ufs-1.1"

			"jedec,ufs-2.0"



- reg		: <registers mapping>

- interrupts	: <interrupt mapping for UFS host controller IRQ>



Example for a setup using a 1.40a DWC Controller with a 6.00 G210 40-bit TC:

	dwc-ufs@d0000000 {

		compatible = "snps,g210-tc-6.00-40bit",

			     "snps,dwc-ufshcd-1.40a",

			     "jedec,ufs-2.0";

		reg = < 0xd0000000 0x10000 >;

		interrupts = < 24 >;

	};
