1 * SPI NOR flash: ST M25Pxx (and similar) serial flash chips
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. A list of supported chip
9 Must also include "jedec,spi-nor" for any SPI NOR flash that can
10 be identified by the JEDEC READ ID opcode (0x9F).
51 The following chip names have been used historically to
52 designate quirky versions of flash chips that do not support the
53 JEDEC READ ID opcode (0x9F):
64 - reg : Chip-Select number
65 - spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at
68 - m25p,fast-read : Use the "fast read" opcode to read data from the chip instead
69 of the usual "read" opcode. This opcode is not supported by
70 all chips and support for it can not be detected at runtime.
71 Refer to your chips' datasheet to check if this is supported
