openwrt/target/linux/bcm27xx/patches-6.6/950-0282-media-i2c-add-ov9281-driver.patch
Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches 
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0282/1085] media: i2c: add ov9281 driver.
Change-Id: I7b77250bbc56d2f861450cf77271ad15f9b88ab1
Signed-off-by: Zefa Chen <zefa.chen@rock-chips.com>
media: i2c: ov9281: fix mclk issue when probe multiple camera.
Takes the ov9281 part only from the Rockchip's patch.
Change-Id: I30e833baf2c1bb07d6d87ddb3b00759ab45a90e4
Signed-off-by: Zefa Chen <zefa.chen@rock-chips.com>
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
Signed-off-by: Zefa Chen <zefa.chen@rock-chips.com>
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
Signed-off-by: Mathias Anhalt <mathiasanhalt@web.de>
Added hflip and vflip controls to ov9281
Signed-off-by: Mathias Anhalt <mathiasanhalt@web.de>
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: Add fwnode properties controls
Add call to v4l2_ctrl_new_fwnode_properties to read and
create the fwnode based controls.

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

Partial revert "media: i2c: add ov9281 driver."
This partially reverts commit 84e98e3a4f3eecb168ceb80231c3e8252929892e.
The commit had merged some changes to other drivers with adding the ov9281
driver. Only the ov9281 parts have been reverted.
