ISSI IS31FL3733 LED Matrix Driver

Properties

Properties not inherited from the base binding file.

Name

Type

Details

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.

sdb-gpios

phandle-array

Hardware shutdown pin. If routed on the board, this property must be
present. Set to a logical 1 at boot to exit the device from hardware
shutdown.

current-limit

int

Global current limit. Sets the global current control register of LED
driver (set table 14). Limits global current based on the following
formula: (840/R_ISET) * (current-limit/256). Defaults to max value
of 0xFF, so led output will still be enabled if property is
not provided.

Default value: 255

sync-mode

string

This property configures the LED controller as a master or slave
clock device. This can be used to synchronize the output of multiple
LED controllers. See SYNC bits in led configuration register for more
information.

Default value: none

Legal values: 'none', 'master', 'slave'
