-Device tree bindings for ARM PL353 static memory controller
-
-PL353 Static Memory Controller is a bus where you can connect two kinds
-of memory interfaces: NAND and memory mapped interfaces (such as SRAM or NOR).
-
-Required properties:
-- compatible		: Should be "arm,pl353-smc-r2p1", "arm,primecell".
-- reg			: SMC controller and sub-controllers configuration
-			  registers.
-- clock-names		: List of input clock names - "memclk", "apb_pclk"
-			  (See clock bindings for details).
-- clocks		: Clock phandles (see clock bindings for details).
-- address-cells		: Must be 2.
-- size-cells		: Must be 1.
-- ranges		: Memory bus areas for interacting with the devices.
-			  Encodes CS to memory region association.
-
-The child device node represents the controller connected to the SMC
-bus. Only one between: NAND controller, NOR controller and SRAM controller
-is allowed in a single system.
-
-Required device node properties:
-
-- reg:			Contains the chip-select id, the offset and the length
-			of the memory region requested by the device.
-
-Example:
-	smcc: memory-controller@e000e000 {
-		compatible = "arm,pl353-smc-r2p1", "arm,primecell";
-		clock-names = "memclk", "apb_pclk";
-		clocks = <&clkc 11>, <&clkc 44>;
-		reg = <0xe000e000 0x1000>;
-		#address-cells = <2>;
-		#size-cells = <1>;
-		ranges = <0x0 0x0 0xe1000000 0x1000000 /* Nand CS region */
-			  0x1 0x0 0xe2000000 0x2000000 /* SRAM/NOR CS0 region */
-			  0x2 0x0 0xe4000000 0x2000000>; /* SRAM/NOR CS1 region */
-
-		nfc0: nand-controller@0,0 {
-			compatible = "arm,pl353-nand-r2p1";
-			reg = <0 0 0x1000000>;
-			#address-cells = <1>;
-			#size-cells = <0>;
-		};
