renesas,smartbond-mipi-dbi

Note

An implementation of a driver matching this compatible is available in drivers/mipi_dbi/mipi_dbi_smartbond.c.

Description

These nodes are “mipi-dbi” bus nodes.

Renesas Smartbond(tm) MIPI DBI Host

Properties

Properties not inherited from the base binding file.

Name	Type	Details
`reset-gpios`	`phandle-array`	Reset GPIO pin. Used to reset the display during initialization.
`te-enable`	`boolean`	Boolean to indicate whether the tearing effect (TE) signal is available or not.
`te-inversion`	`boolean`	Boolean to apply an inversion on the TE signal that triggers the MIPI DBI controller.
`dma-prefetch`	`string`	Host controller will wait for at least the specified number of bytes before triggering a single frame update. The prefetch mechanism should be enabled when frame buffer(s) is stored into external storage mediums, e.g. PSRAM, that introduce comparable delays. In such a case it might case that the controller runs into underrun conditions which results in correpting the whole frame update. It's user's responsibility to ensure that the selected value does not exceed frame's total size as otherwise the controller will not be able to trigger the frame update. Legal values: `'no-prefetch'`, `'prefetch-44-bytes'`, `'prefetch-84-bytes'`, `'prefetch-116-bytes'`, `'prefetch-108-bytes'`
`spi-dev`	`phandle`	SPI bus to use for display read operations. When this property is present, MIPI DBI read operations will be exhibited by the driver. This is because, the LCDC IP block does not support read functionality, natively.
`clock-frequency`	`int`	Clock frequency of the SCL signal of the MBI-DBI peripheral, in Hz
`pinctrl-0`	`phandles`	Pin configuration/s for the first state. Content is specific to the selected pin controller driver implementation.
`pinctrl-1`	`phandles`	Pin configuration/s for the second state. See pinctrl-0.
`pinctrl-2`	`phandles`	Pin configuration/s for the third state. See pinctrl-0.
`pinctrl-3`	`phandles`	Pin configuration/s for the fourth state. See pinctrl-0.
`pinctrl-4`	`phandles`	Pin configuration/s for the fifth state. See pinctrl-0.
`pinctrl-names`	`string-array`	Names for the provided states. The number of names needs to match the number of states.

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 “renesas,smartbond-mipi-dbi” compatible.

Name	Type	Details
`reg`	`array`	register space This property is required. See Important properties for more information.
`interrupts`	`array`	interrupts for device This property is required. See Important properties for more information.
`#address-cells`	`int`	number of address cells in reg property This property is required. Constant value: `1`
`#size-cells`	`int`	number of size cells in reg property This property is required.
`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-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) See Important properties for more information. This property is deprecated.
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`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
`mboxes`	`phandle-array`	mailbox / IPM channels specifiers
`mbox-names`	`string-array`	Provided names of mailbox / IPM channel specifiers
`power-domains`	`phandle-array`	Power domain specifiers
`power-domain-names`	`string-array`	Provided names of power domain specifiers
`#power-domain-cells`	`int`	Number of cells in power-domains property
`zephyr,deferred-init`	`boolean`	Do not initialize device automatically on boot. Device should be manually initialized using device_init().
`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.
`zephyr,pm-device-runtime-auto`	`boolean`	Automatically configure the device for runtime power management after the init function runs.
`zephyr,disabling-power-states`	`phandles`	List of power states that will disable this device power.
