Subject: [PATCH] media: ipu3-cio2: Toggle sensor streaming in pm runtime ops
|
|
|
|
The .suspend() and .resume() runtime_pm operations for the ipu3-cio2
|
|
driver currently do not handle the sensor's stream. Setting .s_stream() on
|
|
or off for the sensor subdev means that sensors will pause and resume the
|
|
stream at the appropriate time even if their drivers don't implement those
|
|
operations.

Subject: [PATCH] media: i2c: Add support for ov5693 sensor
|
|
|
|
The OV5693 is a 5 Mpx CMOS image sensor, connected via MIPI CSI-2. The
|
|
chip is capable of a single lane configuration, but currently only two
|
|
lanes are supported.
|
|
|
|
Most of the sensor's features are supported, with the main exception
|
|
being the lens correction algorithm.
|
|
|
|
The driver provides all mandatory, optional and recommended V4L2 controls
|
|
for maximum compatibility with libcamera.

The sensor orientation is read from the _PLC ACPI buffer and converted
|
|
to a v4l2 format.
|
|
|
|
See https://uefi.org/sites/default/files/resources/ACPI_6_3_final_Jan30.pdf
|
|
page 351 for a definition of the Panel property.
|
|
|
|
The sensor rotation is read from the SSDB ACPI buffer and converted into
|
|
degrees.

Subject: [PATCH] media: i2c: Fix vertical flip in ov5693
|
|
|
|
The pinkness experienced by users with rotated sensors in their laptops
|
|
was due to an incorrect setting for the vertical flip function; the
|
|
datasheet for the sensor gives the settings as bits 1&2 in one place and
|
|
bits 1&6 in another.
|
|
|
|
Switch to flipping bit 6 instead of bit 2 for 0x3820 in the vertical
|
|
flip function to fix the pink hue.

Subject: [PATCH] media: i2c: Add ACPI support to ov8865
|
|
|
|
The ov8865 sensor is sometimes found on x86 platforms enumerated via ACPI.
|
|
Add an ACPI match table to the driver so that it's probed on those
|
|
platforms.

Subject: [PATCH] media: i2c: Check fwnode->secondary for endpoint
|
|
|
|
The ov8865 driver is one of those that can be connected to a CIO2
|
|
device by the cio2-bridge code. This means that the absence of an
|
|
endpoint for this device is not necessarily fatal, as one might be
|
|
built by the cio2-bridge when it probes. Check fwnode->secondary for
|
|
an endpoint, and defer probing if one isn't found rather than fail.

Subject: [PATCH] media: i2c: Support 19.2MHz input clock in ov8865
|
|
|
|
The ov8865 driver as written expects a 24MHz input clock, but the sensor
|
|
is sometimes found on x86 platforms with a 19.2MHz input clock supplied.
|
|
Add a set of PLL configurations to the driver to support that rate too.
|
|
As ACPI doesn't auto-configure the clock rate, check for a clock-frequency
|
|
during probe and set that rate if one is found.

|
Add a V4L2_CID_HBLANK control to the ov8865 driver. This is read only

with timing control intended to be done via vblanking alone.

Subject: [PATCH] media: i2c: cap exposure at height + vblank in ov8865
|
|
|
|
Exposure limits depend on the total height; when vblank is altered (and
|
|
thus the total height is altered), change the exposure limits to reflect
|
|
the new cap.

Subject: [PATCH] media: i2c: Remove unused macros from ov8865
|
|
|
|
There are a number of macros defined in this driver that aren't actually
|
|
used within it. There's a lot of macros defined in total, so removing the
|
|
unused ones helps make it a bit less busy.

Subject: [PATCH] media: i2c: Switch exposure control unit to lines
|
|
|
|
The ov8865 driver currently has the unit of the V4L2_CID_EXPOSURE control
|
|
as 1/16th of a line. This is what the sensor expects, but isn't very
|
|
intuitive. Switch the control to be in units of a line and simply do the
|
|
16x multiplication before passing the value to the sensor.
|
|
|
|
The datasheet for this sensor gives minimum exposure as 2 lines, so take
|
|
the opportunity to correct the lower bounds of the control.

|
|
|
|
ACPI _HID INT347A represents the OV8865 sensor, the driver for which can
|
|
support the platforms that the cio2-bridge serves. Add it to the array
|
|
of supported sensors so the bridge will connect the sensor to the CIO2
|
|
device.
