1 * Ingenic JZ4780 NAND/external memory controller (NEMC)
7 - compatible: Should be set to one of:
8 "ingenic,jz4740-nemc" (JZ4740)
9 "ingenic,jz4780-nemc" (JZ4780)
10 - reg: Should specify the NEMC controller registers location and length.
11 - clocks: Clock for the NEMC controller.
12 - #address-cells: Must be set to 2.
13 - #size-cells: Must be set to 1.
14 - ranges: A set of ranges for each bank describing the physical memory layout.
22 - reg: Should contain at least one register specifier, given in the following
28 for example, for packaged NAND devices with multiple dies. Such devices
32 - ingenic,nemc-bus-width: Specifies the bus width in bits. Defaults to 8 bits.
33 - ingenic,nemc-tAS: Address setup time in nanoseconds.
34 - ingenic,nemc-tAH: Address hold time in nanoseconds.
35 - ingenic,nemc-tBP: Burst pitch time in nanoseconds.
36 - ingenic,nemc-tAW: Access wait time in nanoseconds.
37 - ingenic,nemc-tSTRV: Static memory recovery time in nanoseconds.

52 #address-cells = <2>;
53 #size-cells = <1>;
64 nand: nand@1 {
65 compatible = "ingenic,jz4780-nand";
68 ingenic,nemc-tAS = <10>;
69 ingenic,nemc-tAH = <5>;
70 ingenic,nemc-tBP = <10>;
71 ingenic,nemc-tAW = <15>;
72 ingenic,nemc-tSTRV = <100>;
