EEPROMs (SPI) compatible with Microchip Technology 93xx46 family. |
|
|
|
Required properties: |
|
- compatible : shall be one of: |
|
"atmel,at93c46" |
|
"atmel,at93c46d" |
|
"atmel,at93c56" |
|
"atmel,at93c66" |
|
"eeprom-93xx46" |
|
"microchip,93lc46b" |
|
- 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>; |
|
};
