zephyr,mipi-dbi-spi
Vendor: Zephyr-specific binding
Description
These nodes are “mipi-dbi” bus nodes.
MIPI-DBI Mode C compatible SPI controller. This driver emulates MIPI DBI
mode C using a SPI controller and GPIO pins
Properties
Properties not inherited from the base binding file.

|
|
Clock frequency of the SCL signal of the MBI-DBI peripheral, in Hz
|
|
|
Pin configuration/s for the first state. Content is specific to the
selected pin controller driver implementation.
|
|
|
Pin configuration/s for the second state. See pinctrl-0.
|
|
|
Pin configuration/s for the third state. See pinctrl-0.
|
|
|
Pin configuration/s for the fourth state. See pinctrl-0.
|
|
|
Pin configuration/s for the fifth state. See pinctrl-0.
|
|
|
Names for the provided states. The number of names needs to match the
number of states.
|
|
|
SPI device to use for data transfers with MIPI DBI commands. This SPI
device should be connected to the MIPI DBI display.
This property is required. |
|
|
Data/command gpio pin. Required when using 4 wire SPI mode (Mode C1).
Set to low when sending a command, or high when sending data.
|
|
|
Reset GPIO pin. Set high to reset the display
|
|
|
Only writes to display controller, do not perform reads.
If all controllers are write-only, read functions will be
optimized out for size.
It can also be used as an alternative to half duplex when
only one data line is connected.

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 “zephyr,mipi-dbi-spi” 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.
|
|
|
List of power states that will disable this device power.
|
|
|
indicates the operational status of a device
