Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`pwctrla`	`uint8-array`	Power control A (PWCTRLA) register value. Default value: `[57, 44, 0, 52, 2]`
`pwctrlb`	`uint8-array`	Power control B (PWCTRLB) register value. Default value: `[0, 139, 48]`
`pwseqctrl`	`uint8-array`	Power on sequence control (PWSEQCTRL) register value. Default value: `[85, 1, 35, 1]`
`timctrla`	`uint8-array`	Driver timing control A (TIMCTRLA) register value. Default value: `[132, 17, 122]`
`timctrlb`	`uint8-array`	Driver timing control B (TIMCTRLB) register value. Default value: `[0, 0]`
`pumpratioctrl`	`uint8-array`	Pump ratio control (PUMPRATIOCTRL) register value. Default value: `[16]`
`enable3g`	`uint8-array`	Enable 3G (ENABLE3G) register value. Default value: `[2]`
`etmod`	`uint8-array`	Entry Mode Set (ETMOD) register value. Default value: `[6]`
`gamset`	`uint8-array`	Gamma set (GAMSET) register value. Default value: `[1]`
`frmctr1`	`uint8-array`	Frame rate control (in normal mode / full colors) (FRMCTR1) register value. Default value: `[0, 27]`
`disctrl`	`uint8-array`	Display function control (DISCTRL) register value. Note that changing default SS bit value (0) may interfere with display rotation. Default value: `[10, 130, 39]`
`pwctrl1`	`uint8-array`	Power control 1 (PWCTRL1) register values. Default value: `[33]`
`pwctrl2`	`uint8-array`	Power control 2 (PWCTRL2) register values. Default value: `[16]`
`vmctrl1`	`uint8-array`	VCOM control 1 (VMCTRL1) register values. Default value: `[49, 60]`
`vmctrl2`	`uint8-array`	VCOM control 2 (VMCTRL2) register values. Default value: `[192]`
`pgamctrl`	`uint8-array`	Positive gamma correction (PGAMCTRL) register values. Default value: `[15, 34, 31, 10, 14, 6, 77, 118, 59, 3, 14, 4, 19, 14, 12]`
`ngamctrl`	`uint8-array`	Negative gamma correction (NGAMCTRL) register values. Default value: `[12, 35, 38, 4, 16, 4, 57, 36, 75, 3, 11, 11, 51, 55, 15]`
`reset-gpios`	`phandle-array`	RESET pin. The RESET pin of ILI9340 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 ILI9340 is active low (transmission command byte). If connected directly the MCU pin should be configured as active low. This property is required.
`pixel-format`	`int`	Display pixel format. Note that when RGB888 pixel format is selected only 6 color bits are actually used being in practice equivalent to RGB666. Legal values: `0`, `1`
`rotation`	`int`	Display rotation (CW) in degrees. Legal values: `0`, `90`, `180`, `270`
`display-inversion`	`boolean`	Display inversion mode. Every bit is inverted from the frame memory to the display.
`spi-max-frequency`	`int`	Maximum clock frequency of device's SPI interface in Hz This property is required.
`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.

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 “ilitek,ili9341” 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
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`wakeup-source`	`boolean`	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.
