Kernel-4.18.0-80.el8_microchip,mchp23k256

• 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>;
};
