-Rockchip NAND Flash Controller DT binding
-
-Required properties:
-
-- compatible : "rockchip,rk-nand".
-- reg : shall contain registers location and length for data and reg.
-- interrupts : shall define the nand controller interrupt.
-- clocks : shall reference nand controller clocks.
-- clock-names : nand controller internal clock names. Shall contain :
-    * "hclk_nandc" : AHB gating clock
-    * "clk_nandc" : nand controller clock
-
-Example for rk322x:
-	nandc: nandc@10500000 {
-		compatible = "rockchip,rk-nand";
-		reg = <0x10500000 0x4000>;
-		interrupts = <GIC_SPI 18 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&clk_nandc>, <&clk_gates10 15>;
-		clock-names = "clk_nandc", "hclk_nandc";
-		clock-frequency = <150000000>;
-		status = "okay";
-
-		#address-cells = <1>;
-		#size-cells = <1>;
-		nand@0 {
-			reg = <0>;
-			nand-ecc-mode = "hw";
-			nand-ecc-strength = <16>;
-			nand-ecc-step-size = <1024>;
-		};
