   1* MTD SPI driver for ST M25Pxx (and similar) serial flash chips
   2
   3Required properties:
   4- #address-cells, #size-cells : Must be present if the device has sub-nodes
   5  representing partitions.
   6- compatible : Should be the manufacturer and the name of the chip. Bear in mind
   7               the DT binding is not Linux-only, but in case of Linux, see the
   8               "m25p_ids" table in drivers/mtd/devices/m25p80.c for the list of
   9               supported chips.
  10- reg : Chip-Select number
  11- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at
  12
  13Optional properties:
  14- m25p,fast-read : Use the "fast read" opcode to read data from the chip instead
  15                   of the usual "read" opcode. This opcode is not supported by
  16                   all chips and support for it can not be detected at runtime.
  17                   Refer to your chips' datasheet to check if this is supported
  18                   by your chip.

  20Example:
  21
  22        flash: m25p80@0 {
  23                #address-cells = <1>;
  24                #size-cells = <1>;
  25                compatible = "spansion,m25p80";
  26                reg = <0>;
  27                spi-max-frequency = <40000000>;
  28                m25p,fast-read;
  29        };
