zephyr,mipi-dbi-bitbang
Vendor: Zephyr-specific binding
Note
An implementation of a driver matching this compatible is available in drivers/mipi_dbi/mipi_dbi_bitbang.c.
Description
These nodes are “mipi-dbi” bus nodes.
MIPI-DBI Mode A and B bit banging controller. This driver emulates MIPI DBI mode A and B (6800
and 8080 parallel interfaces) using GPIO pins.
Properties
Properties not inherited from the base binding file.

|
Data/command GPIO pin. Set to low when sending a command, or high when sending data.
This property is required. |
|
|
Reset GPIO pin. Set high to reset the display.
This property is required. |
|
|
Read GPIO pin. Set high when reading from the display. Required for type B (Intel 8080) mode,
unused for type A (Motorola 6800).
|
|
|
Write GPIO pin for type B (Intel 8080) mode, Read/!Write pin for type A (Motorola 6800) mode.
This property is required. |
|
|
Clocked enable/strobe pin for type A (Motorola 6800) mode, unused for type B (Intel 8080).
Fixed E mode is not supported.
|
|
|
Chip-select GPIO pin.
This property is required. |
|
|
GPIO pins used for the parallel data bus. This must have as many entries as the bus is wide
of the selected mipi-mode.
This property is required. |
|
|
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.

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-bitbang” compatible.

Do not initialize device automatically on boot. Device should be manually
initialized using device_init().
|
|
|
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.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
