13description: |
14  The Omnivision OV08X40 is a 9.2 megapixel, CMOS image sensor which supports:
15  - Automatic black level calibration (ABLC)
16  - Programmable controls for frame rate, mirror and flip, binning, cropping
17    and windowing
18  - Output formats 10-bit 4C RGB RAW, 10-bit Bayer RAW
19  - 4-lane MIPI D-PHY TX @ 1 Gbps per lane
20  - 2-lane MPIP D-PHY TX @ 2 Gbps per lane
21  - Dynamic defect pixel cancellation
22  - Standard SCCB command interface
