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