1* NXP Flex Serial Peripheral Interface (FSPI)
2
3Required properties:
4  - compatible : Should be "nxp,lx2160a-fspi"
5			    "nxp,imx8qxp-fspi"
6			    "nxp,imx8mm-fspi"
7			    "nxp,imx8mp-fspi"
8			    "nxp,imx8dxl-fspi"
9
10  - reg :        First contains the register location and length,
11                 Second contains the memory mapping address and length
12  - reg-names :  Should contain the resource reg names:
13	         - fspi_base: configuration register address space
14                 - fspi_mmap: memory mapped address space
15  - interrupts : Should contain the interrupt for the device
16
17Required SPI slave node properties:
18  - reg :        There are two buses (A and B) with two chip selects each.
19                 This encodes to which bus and CS the flash is connected:
20                 - <0>: Bus A, CS 0
21                 - <1>: Bus A, CS 1
22                 - <2>: Bus B, CS 0
23                 - <3>: Bus B, CS 1

25Example showing the usage of two SPI NOR slave devices on bus A:
26
27fspi0: spi@20c0000 {
28	compatible = "nxp,lx2160a-fspi";
29	reg = <0x0 0x20c0000 0x0 0x10000>, <0x0 0x20000000 0x0 0x10000000>;
30	reg-names = "fspi_base", "fspi_mmap";
31	interrupts = <0 25 0x4>; /* Level high type */
32	clocks = <&clockgen 4 3>, <&clockgen 4 3>;
33	clock-names = "fspi_en", "fspi";
34
35	mt35xu512aba0: flash@0 {
36		reg = <0>;
37		....
38	};
39
40	mt35xu512aba1: flash@1 {
41		reg = <1>;
42		....
43	};
44};
