[libcamera-devel] [PATCH 1/2] libipa: Add CameraSensorHelper for ov2680

[Daniel Scally]

Add a CameraSensorHelperOv2680 class. The OV2680 is found in concert
with an IPU3 on the Lenovo Miix 510. The constants set are a bit of a
guess, as the datasheet doesn't document the gain control field any
further than giving its width in bits, but the default is 0x10 so we
assume that to be 1x gain.
