Dingenic,jz4780-nemc.txt1 * Ingenic JZ4780 NAND/external memory controller (NEMC)
3 This file documents the device tree bindings for the NEMC external memory
7 - compatible: Should be set to one of:
8 "ingenic,jz4780-nemc" (JZ4780)
9 - reg: Should specify the NEMC controller registers location and length.
10 - clocks: Clock for the NEMC controller.
11 - #address-cells: Must be set to 2.
12 - #size-cells: Must be set to 1.
13 - ranges: A set of ranges for each bank describing the physical memory layout.
18 Each child of the NEMC node describes a device connected to the NEMC.
