-* 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 one of "microchip,mchp23k256" or "microchip,mchp23lcv1024"
-- 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>;
-	};

+description: |
+  Driver for Microchip 23K256 and compatible (e.g. 23LCV1024) serial SRAM devices
+  accessed via SPI. The device exposes the SRAM as an MTD device and supports
+  optional partitioning via child nodes.
