This is a 1.5M pixel global shutter camera available in both Mono (VD56G3) and colour (VD66GY) variants. The following features are supported: - Auto exposure with expo bias or - Manual exposure with analog / digital gain - H/V flip - vblank/hblank/link freq - Test pattern - Supported resolutions in both raw8/raw10 : - 1124x1364 - 1120x1360 - 1024x1280 - 1024x768 - 768x1024 - 720x1280 - 640x480 - 480x640 - 320x240 This driver supports coldstart parameters for internal AE feature. To make it work, the driver save gain/expo values in ctrl's cur.val during poweroff phase. This implementation transgress V4L2 rules... Any advice to make it proper would be greatly appreciated. Driver tested on RB5 and RPI (with and without libcamera) for V1. V2, V3, V4 and V5 mainly tested on RPI. --- v4 -> v5 Following Sakari's comment on VD55G1 series [1], use device_property*() instead of of_property*() and drop OF dependency.
