|
+
|
|
|
+Required properties:
|
|
|
+- compatible : "allwinner,sun4i-a10-nand".
|
|
|
+- reg : shall contain registers location and length for data and reg.
|
|
|
+- interrupts : shall define the nand controller interrupt.
|
|
|
+- #address-cells: shall be set to 1. Encode the nand CS.
|
|
|
+- #size-cells : shall be set to 0.
|
|
|
+- clocks : shall reference nand controller clocks.

|
|
+- clock-names : nand controller internal clock names. Shall contain :
|
|
|
+ * "ahb" : AHB gating clock
|
|
|
+ * "mod" : nand controller clock
|
|
|

|
|
|
+Optional children nodes:
|
|
|
+Children nodes represent the available nand chips.
