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