[libcamera-devel] Pinephone 1.2 and libcamera

Tue Jun 28 11:02:28 CEST 2022

I tried to first just copy the ov5640.c to my 5.15 branch, and the error 
message from libcamera changed. Now I get:

WARN CameraSensor camera_sensor.cpp:212 'ov5640 3-004c': Recommended 
V4L2 control 0x009a0922 not supported
WARN CameraSensor camera_sensor.cpp:264 'ov5640 3-004c': The sensor 
kernel driver needs to be fixed
WARN CameraSensor camera_sensor.cpp:266 'ov5640 3-004c': See 
Documentation/sensor_driver_requirements.rst in the libcamera sources 
for more information
WARN CameraSensor camera_sensor.cpp:411 'ov5640 3-004c': Failed to 
retrieve the camera location

ERROR V4L2 v4l2_videodevice.cpp:1076 /dev/video2[10:cap]: Media bus code 
filtering not supported by the device
(this last error repeats more than 50 times ^^^^)

ERROR SimplePipeline simple.cpp:490 No valid configuration found

May be I'm missing something in order to backport the ov5640 driver to 
the 5.15 branch?

Thanks,
Rafael Diniz
