2
3Required properties:
4- #address-cells, #size-cells : Must be present if the device has sub-nodes
5  representing partitions.
6- compatible : Must be one of "microchip,mchp23k256" or "microchip,mchp23lcv1024"
7- reg : Chip-Select number
8- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at

12	spi-sram@0 {
13		#address-cells = <1>;
14		#size-cells = <1>;
15		compatible = "microchip,mchp23k256";
16		reg = <0>;
17		spi-max-frequency = <20000000>;
