From: Nicholas Roth <nicholas@xxxxxxxxxxxxx> Add a driver for OmniVision OV8858 image sensor. The driver currently supports operations with 2 and 4 data lanes, in full resolution and half-binned resolution modes. The driver has been upported from the PinephonePro BSP available at https://gitlab.com/pine64-org/linux.git at commit 8c4a90c12dc2 ("media: i2c: ov8858: Use default subdev name").
