4   - compatible : Should be "nxp,lx2160a-fspi"
5 			    "nxp,imx8qxp-fspi"
6 			    "nxp,imx8mm-fspi"
8   - reg :        First contains the register location and length,
10   - reg-names :  Should contain the resource reg names:
11 	         - fspi_base: configuration register address space
12                  - fspi_mmap: memory mapped address space
13   - interrupts : Should contain the interrupt for the device
15 Required SPI slave node properties:
16   - reg :        There are two buses (A and B) with two chip selects each.
17                  This encodes to which bus and CS the flash is connected:
18                  - <0>: Bus A, CS 0
19                  - <1>: Bus A, CS 1
20                  - <2>: Bus B, CS 0
21                  - <3>: Bus B, CS 1
23 Example showing the usage of two SPI NOR slave devices on bus A:
25 fspi0: spi@20c0000 {
26 	compatible = "nxp,lx2160a-fspi";
28 	reg-names = "fspi_base", "fspi_mmap";
29 	interrupts = <0 25 0x4>; /* Level high type */
31 	clock-names = "fspi_en", "fspi";
