[libcamera-devel] [PATCH] libcamera: add hi846 camera sensor properties

[Martin Kepplinger]

Add camera sensor properties for the Hynix hi846 sensor.
The part is also called YACG4D0C9SHC and a datasheet can be found at
https://product.skhynix.com/products/cis/cis.go

This is the selfie camera in the Librem 5 phone.

Signed-off-by: Martin Kepplinger <martin.kepplinger at puri.sm>

Note that the driver is not yet merged into the mainline but being
reviewed:
https://lore.kernel.org/linux-media/20210831134344.1673318-1-martin.kepplinger@puri.sm/
libcamera doesn't warn about anything when using the camera. `cam` streams
and qcam shows a (non-debayered) image.

thanks,
                  martin
