** Description changed:
+ [ SRU Justification ]
+
+ [ Impact ]
+
+ OV08x40, added in v6.2 kernel, has inverted hflip regiter written in
+ `ov08x40_set_ctrl_vflip`. This is fixed by v6.18-rc1 commit
+ c7df6f339af94 ("media: ov08x40: Fix the horizontal flip control").
+
+ [ Test Plan ]
+
+ 1. Install patched kernel from -proposed kernel and reboot into it.
+
+ 2. Find out the device name for ov08x40:
+ ```
+ $ grep -nr ov08x40 /sys/class/video4linux/*/name
+ /sys/class/video4linux/v4l-subdev6/name:1:ov08x40 17-0010
+
+ $ sudo v4l2-ctl -l -d /dev/v4l-subdev6
+
+ User Controls
+
+ exposure 0x00980911 (int) : min=4 max=4992 step=1 default=4992
value=2470 flags=0x00001000
+ horizontal_flip 0x00980914 (bool) : default=0 value=0 flags=0x00001000
+ vertical_flip 0x00980915 (bool) : default=0 value=0 flags=0x00001000
+ ......
+ ```
+
+ 3. Set horizontal flip to 1. The original driver won't have any effect on
this step, but the patched driver should have video output flipped horizontally:
+ ```
+ $ sudo v4l2-ctl -c horizontal_flip=1 -d /dev/v4l-subdev6
+ horizontal_flip: 0
+ $ sudo v4l2-ctl -C horizontal_flip -d /dev/v4l-subdev6
+ horizontal_flip: 1
+
+ ```
+
+ 4. Use camera app to examine the output. Here an Intel MIPI camera platform
with ov08x40 camera sensor is used:
+ ```
+ $ sudo gst-launch-1.0 icamerasrc ! videoconvert ! autovideosink
+ ```
+
+ [ Where problems could occur ]
+
+ No. This writes the right value intro device register only.
+
+ [ Other Info ]
+
+ While ov08x40 was added at v6.2, nominate for kernels newer than that.
+
+ ========= original bug report ==========
+
OV08x40, added in v6.2 kernel, has inverted hflip regiter written in
`ov08x40_set_ctrl_vflip`. This is fixed by v6.18-rc1 commit
c7df6f339af94 ("media: ov08x40: Fix the horizontal flip control").
In bug 2084059, an out-of-tree revision of ov08x40 was added to
ipu6-drivers, and kernel ipu-bridge supported sensors was updated. While
now the in-tree ov08x40 has been updated to natively support enabled oem
devices, switch to the in-tree driver whenever possible.
