Dahua-OEM 2 MP camera. The SC223A is on hardware I2C0 routed to the VI-RAW pads (0x112c0060/0x64 func2) rather than the default mipi-sensor pads (0x30/0x34 func1) the SDK probes, and needs a 27 MHz MCLK (0x120100f0=0x19; SDK default 0x11/div4 leaves it unresponsive). S71devmem re-muxes the pads, selects the SENSOR_RSTN reset (GPIO8_7 func2) and fixes MCLK after S70vendor/load_goke; the stock open_sensor_i2c then reaches the sensor over /dev/i2c-0. No kernel module needed. Verified on hardware: chip-id 0xcb3e over HW I2C0, MIPI lock 1920x1080 zero errors, majestic streams correct colour 1080p.
