Properties

Node specific properties

Base properties

Properties not inherited from the base binding file.

Name	Type	Details
data_cmd-gpios	phandle-array	D/C# pin. This property is required.
height	int	Height in pixel of the panel driven by the controller This property is required.
width	int	Width in pixel of the panel driven by the controller This property is required.
segment-offset	int	8-bit column start address for Page Addressing Mode This property is required.
page-offset	int	Start address for Page Addressing Mode This property is required.
display-offset	int	mapping of the display start line to one of COM0 .. COM63 This property is required.
multiplex-ratio	int	Multiplex Ratio This property is required.
segment-remap	boolean	Last column address is mapped to first segment
com-invdir	boolean	Scan direction is from last COM output to first COM output
com-sequential	boolean	Sequential COM pin configuration
prechargep	int	Duration of the pre-charge period This property is required.
reset-gpios	phandle-array	RESET pin. The RESET pin of SSD1306 is active low. If connected directly the MCU pin should be configured as active low.
spi-max-frequency	int	Maximum clock frequency of device's SPI interface in Hz This property is required.
supply-gpios	phandle	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.

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.

Name	Type	Details
reg	array	register space This property is required. See Important properties for more information.
label	string	Human readable string describing the device (used as device_get_binding() argument) This property is required. See Important properties for more information.
status	string	indicates the operational status of a device Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss' See Important properties for more information.
compatible	string-array	compatible strings This property is required. See Important properties for more information.
reg-names	string-array	name of each register space
interrupts	array	interrupts for device See Important properties for more information.
interrupts-extended	compound	extended interrupt specifier for device
interrupt-names	string-array	name of each interrupt
interrupt-parent	phandle	phandle to interrupt controller node
clocks	phandle-array	Clock gate information
clock-names	string-array	name of each clock
#address-cells	int	number of address cells in reg property
#size-cells	int	number of size cells in reg property
dmas	phandle-array	DMA channels specifiers
