+Rockchip NANDC Controller for SOC
+
+Required properties:
+- compatible : "rockchip,nandc".
+- reg : shall contain registers location and length for data and reg.
+- interrupts : shall define the nandc controller interrupt.
+- clocks : shall reference nandc controller clocks.
+- clock-names : nandc controller internal clock names. Shall contain :
+    * "clk_nandc" : nand controller clock
+    * "hclk_nandc" : nandc ahb clock gate
+    * "g_clk_nandc" : nandc enable clock gate
+
+Examples:
