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