The Macronix Multi-Interface Raw NAND Controller is a versatile flash
15
+
memory controller for embedding in SoCs, capable of interfacing with
16
+
various NAND devices. It requires dedicated clock inputs for core, data
17
+
transmit, and delayed transmit paths along with register space and an
18
+
interrupt line for operation.

Macronix Raw NAND Controller Device Tree Bindings
2
-
-------------------------------------------------
3
-
4
-
Required properties:
5
-
- compatible: should be "mxic,multi-itfc-v009-nand-controller"
6
-
- reg: should contain 1 entry for the registers
7
-
- #address-cells: should be set to 1
8
-
- #size-cells: should be set to 0
9
-
- interrupts: interrupt line connected to this raw NAND controller
10
-
- clock-names: should contain "ps", "send" and "send_dly"
11
-
- clocks: should contain 3 phandles for the "ps", "send" and
12
-
"send_dly" clocks
13

-
Children nodes:
15
-
- children nodes represent the available NAND chips.
