Sony IMX678 is an 8.4 Megapixel (3856x2180) CMOS sensor, that can output pixels over MIPI CSI-2 bus. Add bindings for it. Runtime detection for mono vs color variant of this sensor is feasible by reading a register, but it's not always desirable given the sensor needs to be powered on for it, potentially flashing a privacy LED or wasting precious boot time. The manufacturer or vendor knows which sensor variant they are putting on their board, so we define the compatible property to expect the (color/mono) specific name of the sensor, along with a generic fallback.

Add a V4L2 subdev driver for the Sony IMX678 image sensor. IMX678 is a diagonal 8.86 mm (Type 1/1.8) CMOS active pixel type solid-state image sensor with a square pixel array and 8.40 M effective pixels. The following features are supported by this driver: - MIPI RAW12 output - Monochrome and Color (Bayer filter) variants - Multiple input clock frequencies - Multiple link frequencies - VBLANK and HBLANK control for variable framerate - VFLIP and HFLIP control for flipping readout - Exposure and analogue gain control - Test pattern control Following features are not currently supported: - MIPI RAW10 output - Pixel-perfect crop reporting, accounting for the shift-by-1 when doing HFLIP/VFLIP where the sensor maintains RGGB bayer ordering Along with the ones below which depend on the new raw sensor model: - Embedded data stream - Freely configurable cropping - Increased framerate when cropping - 2x2 binning support Signed-off-by: Jai Luthra <jai.luthra@ideasonboard.com> Reviewed-by: Tarang Raval <tarang.raval@siliconsignals.io> [Sakari Ailus: Add an extra newline to the enum_mbus_code op.] Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com>
The register layout and programming model for multiple of the Sony Starvis2 sensors is identical, so prepare for supporting those by renaming all common parts of the driver to a starvis2_ prefix, and renaming the driver. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
link_freqs_reg_value is table that just reverses the order of the link frequency enum. Reverse the order of the link frequencies so that the table is redundant, and remove it. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
If the requested region matched the defined active area then the driver switched to all-pixel mode. This left the possibility that the activeare was incorrect and not reading out the area expected. Switch to always requesting window mode. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
…er models Several of the Sony Starvis 2 sensors are identical in the majority of their programming, but differ largely only in the size of pixel array and some timing parameters. Parameterise those parameters in preparation for supporting other variants. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
IMX662 is a 1080p Starvis 2 sensor that follows the same programming pattern as IMX678, so add it to the newly parameterised common driver. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
The IMX675 is a 5MPix Starvis2 sensor that follows the same programming pattern as IMX678 and IMX662, so add it into the driver. Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>

Working with IMX662, although only at 32.86fps at present (doubling HMAX for all link frequencies is erroneous), and missing HGC selection (won't be acceptable to upstream in current form). |

6.18 backport of IMX678 driver from 7.3 (needs upstream commit hashes), and then amend to become a generic Starvis 2 driver supporting IMX678 (8MPix), IMX675 (5MPix), IMX662 (2MPix), and eventually IMX585 and IMX832. Includes overlays for each of the supported sensors.
