Properties

Node specific propertiesDeprecated node specific propertiesBase 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.
spi-max-frequency	int	Maximum clock frequency of device's SPI interface in Hz This property is required.
duplex	int	Duplex mode, full or half. By default it's always full duplex thus 0 as this is, by far, the most common mode. Use the macros not the actual enum value, here is the concordance list (see dt-bindings/spi/spi.h) 0 SPI_FULL_DUPLEX 2048 SPI_HALF_DUPLEX Legal values: 0, 2048
frame-format	int	Motorola or TI frame format. By default it's always Motorola's, thus 0 as this is, by far, the most common format. Use the macros not the actual enum value, here is the concordance list (see dt-bindings/spi/spi.h) 0 SPI_FRAME_FORMAT_MOTOROLA 32768 SPI_FRAME_FORMAT_TI Legal values: 0, 32768
spi-cpol	boolean	SPI clock polarity which indicates the clock idle state. If it is used, the clock idle state is logic high; otherwise, low.
spi-cpha	boolean	SPI clock phase that indicates on which edge data is sampled. If it is used, data is sampled on the second edge; otherwise, on the first edge.
spi-hold-cs	boolean	In some cases, it is necessary for the master to manage SPI chip select under software control, so that multiple spi transactions can be performed without releasing it. A typical use case is variable length SPI packets where the first spi transaction reads the length and the second spi transaction reads length bytes.
height	int	Height of the panel driven by the controller, with the units in pixels. This property is required.
width	int	Width of the panel driven by the controller, with the units in pixels. This property is required.
reset-gpios	phandle-array	RESET pin. The RESET pin of ST7735R is active low. If connected directly the MCU pin should be configured as active low.
cmd-data-gpios	phandle-array	D/CX pin. The D/CX pin of ST7735R is active low (transmission command byte). If connected directly the MCU pin should be configured as active low. This property is required.
x-offset	int	The column offset in pixels of the LCD to the controller memory This property is required.
y-offset	int	The row offset in pixels of the LCD to the controller memory This property is required.
madctl	int	Memory Data Access Control
colmod	int	Interface Pixel Format Default value: 6
pwctr1	uint8-array	Power Control 1 Parameter Default value: [180, 20, 4]
pwctr2	uint8-array	Power Control 2 Parameter Default value: [192]
pwctr3	uint8-array	Power Control 3 Parameter Default value: [10, 0]
pwctr4	uint8-array	Power Control 4 Parameter Default value: [138, 38]
pwctr5	uint8-array	Power Control 5 Parameter Default value: [138, 238]
gamctrp1	uint8-array	Positive Voltage Gamma Control Parameter This property is required.
gamctrn1	uint8-array	Negative Voltage Gamma Control Parameter This property is required.
frmctr1	uint8-array	Frame rate control (normal mode / full colors) Default value: [5, 58, 58]
frmctr2	uint8-array	Frame rate control (idle mode / 8 colors) Default value: [5, 58, 58]
frmctr3	uint8-array	Frame rate control (partial mode / full colors) Default value: [5, 58, 58, 5, 58, 58]
caset	uint8-array	Column Address Set Default value: [0, 0, 0, 127]
raset	uint8-array	Row Address Set Default value: [0, 0, 0, 159]
vmctr1	int	VCOM Control 1 Default value: 10
invctr	int	Display Inversion Control Set dot inversion or line inversion for each normal/idle/partial mode. Default value: 7
inversion-on	boolean	Enable Display Inversion Make a drawing with the inverted color of the frame memory.
rgb-is-inverted	boolean	Inverting color format order (RGB->BGR or BGR->RGB) In the case of enabling this option, API reports pixel-format in capabilities as the inverted value of the RGB pixel-format specified in MADCTL. This option is convenient for supporting displays with bugs where the actual color is different from the pixel format of MADCTL.
