Description

Atmel AT24 (or compatible) I2C EEPROM

Properties

Properties not inherited from the base binding file.

Name

Type

Details

size

int

 
Total EEPROM size in bytes

This property is required.

read-only

boolean

 
Disable writes to the EEPROM

pagesize

int

 
EEPROM page size in bytes

This property is required.

address-width

int

 
EEPROM address width in bits

This property is required.

timeout

int

 
EEPROM write cycle timeout in milliseconds

This property is required.

wp-gpios

phandle-array

 
GPIO to which the write-protect pin of the chip is connected.

The device will interpret this signal as active-low.

supply-gpios

phandle-array

 
GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

 
Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.
