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 : May include a device-specific string consisting of the
7               manufacturer and name of the chip. Bear in mind the DT binding
8               is not Linux-only, but in case of Linux, see the "m25p_ids"
9               table in drivers/mtd/devices/m25p80.c for the list of supported
10               chips.
11               Must also include "jedec,spi-nor" for any SPI NOR flash that can
12               be identified by the JEDEC READ ID opcode (0x9F).
13- reg : Chip-Select number
14- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at
15
16Optional properties:
17- m25p,fast-read : Use the "fast read" opcode to read data from the chip instead
18                   of the usual "read" opcode. This opcode is not supported by
19                   all chips and support for it can not be detected at runtime.
20                   Refer to your chips' datasheet to check if this is supported
21                   by your chip.

23Example:
24
25	flash: m25p80@0 {
26		#address-cells = <1>;
27		#size-cells = <1>;
28		compatible = "spansion,m25p80", "jedec,spi-nor";
29		reg = <0>;
30		spi-max-frequency = <40000000>;
31		m25p,fast-read;
32	};
