+* MTD SPI driver for Microchip 23K256 (and similar) serial SRAM
+
+Required properties:
+- #address-cells, #size-cells : Must be present if the device has sub-nodes
+ representing partitions.
+- compatible : Must be "microchip,mchp23k256"
+- reg : Chip-Select number
+- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at
+
+Example:
+
+ spi-sram@0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "microchip,mchp23k256";
+ reg = <0>;
+ spi-max-frequency = <20000000>;
+ };
