Description

Fujitsu MB85RCXX series I2C FRAM

Properties

Properties not inherited from the base binding file.

Name

Type

Details

size

int

Total FRAM size in bytes.

This property is required.

pagesize

int

Size of the single FRAM module in bytes.
If not provided it is assumed to be the same as total size.

address-width

int

FRAM address width in bits.

This property is required.

wp-gpios

phandle-array

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

read-only

boolean

Disable writes to the EEPROM

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.
