1 EEPROMs (SPI) compatible with Atmel at25. 2 3 Required properties: 4 - compatible : "atmel,at25". 5 - reg : chip select number 6 - spi-max-frequency : max spi frequency to use 7 - pagesize : size of the eeprom page 8 - size : total eeprom size in bytes 9 - address-width : number of address bits (one of 8, 16, or 24) 10 11 Optional properties: 12 - spi-cpha : SPI shifted clock phase, as per spi-bus bindings. 13 - spi-cpol : SPI inverse clock polarity, as per spi-bus bindings. 14 - read-only : this parameter-less property disables writes to the eeprom 15 16 Obsolete legacy properties are can be used in place of "size", "pagesize", 17 "address-width", and "read-only": 18 - at25,byte-len : total eeprom size in bytes 19 - at25,addr-mode : addr-mode flags, as defined in include/linux/spi/eeprom.h 20 - at25,page-size : size of the eeprom page 21 22 Additional compatible properties are also allowed. 23 24 Example: 25 at25@0 { 26 compatible = "atmel,at25", "st,m95256"; 27 reg = <0> 28 spi-max-frequency = <5000000>; 29 spi-cpha; 30 spi-cpol; 31 32 pagesize = <64>; 33 size = <32768>; 34 address-width = <16>; 35 };
