-Rockchip NAND Flash Controller DT binding
-
-Required properties:
-
-- compatible : "rockchip,rk-nand-v9".
-- 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 rk3326 / rkpx30:
-	nandc0: nandc@ff3b0000 {
-		compatible = "rockchip,rk-nandc-v9";
