1 EEPROMs (SPI) compatible with Atmel at25.
4 - compatible : Should be "<vendor>,<type>", and generic value "atmel,at25".
5 Example "<vendor>,<type>" values:
11 - reg : chip select number
12 - spi-max-frequency : max spi frequency to use
13 - pagesize : size of the eeprom page
14 - size : total eeprom size in bytes
15 - address-width : number of address bits (one of 8, 9, 16, or 24).
16 For 9 bits, the MSB of the address is sent as bit 3 of the instruction
17 byte, before the address byte.
20 - spi-cpha : SPI shifted clock phase, as per spi-bus bindings.
21 - spi-cpol : SPI inverse clock polarity, as per spi-bus bindings.
22 - read-only : this parameter-less property disables writes to the eeprom
24 Obsolete legacy properties can be used in place of "size", "pagesize",
25 "address-width", and "read-only":
26 - at25,byte-len : total eeprom size in bytes
27 - at25,addr-mode : addr-mode flags, as defined in include/linux/spi/eeprom.h
28 - at25,page-size : size of the eeprom page
30 Additional compatible properties are also allowed.
