ovti,ov5640 (on i2c bus)
Vendor: OmniVision Technologies Co., Ltd.
Note
An implementation of a driver matching this compatible is available in drivers/video/ov5640.c.
Description
OV5640 CMOS video sensor
Properties
Top level properties
These property descriptions apply to “ovti,ov5640” nodes themselves. This page also describes child node properties in the following sections.
Node specific properties
Properties not inherited from the base binding file.
Name |
Type |
Details |
|---|---|---|
|
|
The RESETB pin is asserted to cause a hard reset. The sensor
receives this as an active-low signal.
|
|
|
The PWDN pin is asserted to disable the sensor. The sensor
receives this as an active-high signal.
|
|
|
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.
|
|
|
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.

Deprecated node specific properties
Deprecated properties not inherited from the base binding file.
(None)
Base properties
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 “ovti,ov5640” 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.

|
|
Label of the 'remote-endpoint' subnode that interfaces with this endpoint.
This property is used as a 'work-around' to be able to declare the remote
endpoint and should be replaced by a "remote-endpoint" phandle property when
Zephyr devicetree supports circular dependency in the future.
This property is required. |
|
|
Data bus type.
Legal values: |
|
|
On parallel data busses, if bus-width is used to specify the number of
data lines, data-shift can be used to specify which data lines are used,
e.g. "bus-width=<8>; data-shift=<2>;" means, that lines 9:2 are used.
|
|
|
Active state of the HSYNC signal
Legal values: |
|
|
Active state of the VSYNC signal.
Legal values: |
|
|
Sample data on falling, rising or both edges of the pixel clock signal.
Legal values: |
|
|
Allowed data bus frequencies. For MIPI CSI-2, for instance, this is the
actual frequency of the bus, not bits per clock per lane value.
|
|
|
Physical clock lane index. Position of an entry determines the logical
lane number, while the value of an entry indicates physical lane, e.g. for
a MIPI CSI-2 bus we could have "clock-lane = <0>;", which places the
clock lane on hardware lane 0. This property is valid for serial busses
only (e.g. MIPI CSI-2).
|
|
|
An array of physical data lane indexes. Position of an entry determines
the logical lane number, while the value of an entry indicates physical
lane, e.g. for 2-lane MIPI CSI-2 bus we could have "data-lanes = <1 2>;",
assuming the clock lane is on hardware lane 0. If the hardware does not
support lane reordering, monotonically incremented values shall be used
from 0 or 1 onwards, depending on whether or not there is also a clock
lane. This property is valid for serial busses only (e.g. MIPI CSI-2).
|
|
|
Number of data lines actively used, only valid for parallel busses.
