media: i2c: Add a driver for the Infineon IRS1125 depth sensor

Browse Source 
The Infineon IRS1125 is a time of flight depth sensor that
has a CSI-2 interface.

Add a V4L2 subdevice driver for this device.

media: irs1125: Using i2c_transfer for ic2 reads

Reading data over i2c is done by using i2c_transfer to ensure that this
operation can't be interrupted.

media: irs1125: Refactoring and debug messages

Changed some variable names to comply with checkpatch --strict mode.
Debug messages added.

media: irs1125: Atomic access to imager reconfiguration

Instead of changing the exposure and framerate settings for all sequences,
they can be changed for every sequence individually now. Therefore the
IRS1125_CID_SAFE_RECONFIG ctrl has been removed and replaced by
IRS1125_CID_SAFE_RECONFIG_S<seq_num>_EXPO and *_FRAME ctrls.

The consistency check in the sequence ctrl IRS1125_CID_SEQ_CONFIG
is removed.

media: irs1125: Keep HW in sync after imager reset

When closing the video device, the irs1125 is put in power down state.
To keep V4L2 ctrls and the HW in sync, v4l2_ctrl_handler_setup is
called after power up.

The compound ctrl IRS1125_CID_MOD_PLL however has a default value
of all zeros, which puts the imager into a non responding state.
Thus, this ctrl is not written by the driver into HW after power up.
The userspace has to take care to write senseful data.

media: i2c: add ov9281 driver.

media: i2c: ov9281: fix mclk issue when probe multiple camera.

Takes the ov9281 part only from the Rockchip's patch.

media: i2c: ov9281: add enum_frame_interval function for iq tool 2.2 and hal3

Adds the ov9281 parts of the Rockchip patch adding enum_frame_interval to
a large number of drivers.

Change-Id: I03344cd6cf278dd7c18fce8e97479089ef185a5c

media: i2c: ov9281: Fixup for recent kernel releases, and remove custom code

The Rockchip driver was based on a 4.4 kernel, and had several custom
Rockchip parts.

Update to 5.4 kernel APIs, with the relevant controls required by
libcamera, and remove custom Rockchip parts.

media: i2c: ov9281: Read chip ID via 2 reads

Vision Components have made an OV9281 module which blocks reading
back the majority of registers to comply with NDAs, and in doing
so doesn't allow auto-increment register reading as used when
reading the chip ID.

Use two reads and manually combine the results.

media: i2c: ov9281: Add support for 8 bit readout

The sensor supports 8 bit mode as well as 10bit, so add the
relevant code to allow selection of this.

media: ov9281: Add 1280x720 and 640x480 modes

Breaks out common register set and adds the different registers
for 1280x720 (cropped) and 640x480 (skipped) modes

Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>

Fixed picture line bug in all ov9281 modes

Added hflip and vflip controls to ov9281

media: i2c: ov9281: Remove override of subdev name

From the original Rockchip driver, the subdev was renamed
from the default to being "mov9281 <dev_name>" whereas the
default would have been "ov9281 <dev_name>".

Remove the override to drop back to the default rather than
a vendor custom string.

media: i2c: ov9281: Sensor should report RAW color space

Tested on Raspberry Pi running libcamera.

Signed-off-by: David Plowman <david.plowman@raspberrypi.com>

Partial revert "media: i2c: add ov9281 driver."

This partially reverts commit 84e98e3a4f.

The commit had merged some changes to other drivers with adding the ov9281
driver. Only the ov9281 parts have been reverted.
