1EEPROMs (SPI) compatible with Microchip Technology 93xx46 family. 2 3Required properties: 4- compatible : shall be one of: 5 "atmel,at93c46d" 6 "eeprom-93xx46" 7 "microchip,93lc46b" 8- data-size : number of data bits per word (either 8 or 16) 9 10Optional properties: 11- read-only : parameter-less property which disables writes to the EEPROM 12- select-gpios : if present, specifies the GPIO that will be asserted prior to 13 each access to the EEPROM (e.g. for SPI bus multiplexing) 14 15Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt 16apply. In particular, "reg" and "spi-max-frequency" properties must be given. 17 18Example: 19 eeprom@0 { 20 compatible = "eeprom-93xx46"; 21 reg = <0>; 22 spi-max-frequency = <1000000>; 23 spi-cs-high; 24 data-size = <8>; 25 select-gpios = <&gpio4 4 GPIO_ACTIVE_HIGH>; 26 }; 27
