Height of the panel driven by the controller, with the units in pixels.
This property is required. |
|
|
Width of the panel driven by the controller, with the units in pixels.
This property is required. |
|
|
8-bit column start address for Page Addressing Mode
This property is required. |
|
|
Start address for Page Addressing Mode
This property is required. |
|
|
mapping of the display start line to one of COM0 .. COM63
This property is required. |
|
|
Multiplex Ratio
This property is required. |
|
|
Last column address is mapped to first segment
|
|
|
Scan direction is from last COM output to first COM output
|
|
|
Sequential COM pin configuration
|
|
|
Duration of the pre-charge period
This property is required. |
|
|
RESET pin.
The RESET pin of SSD1306 is active low. If connected directly the MCU pin should be configured as active low.
|
|
|
Turn on display color inverting
|
|
|
Time it takes for the device from power up to become responsive and
accepting commands. Defaults to 10ms (found by trial and error) if not
provided.
Default value: |
|
|
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.
|
|
|
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.
|
Deprecated properties not inherited from the base binding file.
(None)
Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “solomon,ssd1306fb” compatible.

|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
