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.

description: |

|
|
|
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.
