13description: |-
14  The Omnivision OV02A10 is a low-cost, high performance, 1/5-inch, 2 megapixel
15  image sensor, which is the latest production derived from Omnivision's CMOS
16  image sensor technology. Ihis chip supports high frame rate speeds up to 30fps
17  @ 1600x1200 (UXGA) resolution transferred over a 1-lane MIPI interface. The
18  sensor output is available via CSI-2 serial data output.

59      or shutdown mode. As the line needs to be high for the powerdown mode
