The ov5670 driver registers three controls as read-only: - V4L2_CID_PIXEL_RATE - V4L2_CID_LINK_FREQ - V4L2_CID_HBLANK The driver updates the range of HBLANK with __v4l2_ctrl_modify_range() and updates the values of PIXEL_RATE and LINK_FREQ with an explicit call to __v4l2_ctrl_s_ctrl() in ov5670_set_pad_format() time. This causes the .set_ctrl handler to be called on these controls causing a non-fatal warning to be emitted: ov5670_set_ctrl Unhandled id:0x9e0902, val:0x824 This is currently only critical for HBLANK, as LINK_FREQ and PIXEL_RATE currently only support a single value, and the v4l2-ctrl framework skips calling .set_ctrl() if the current control value is not changed. Expand the ov5670_set_ctrl() callback to handle the above controls to remove the above warning and defend against future expansions of the supported pixel rates and link frequencies. Also be stricter and return an error value if a control is actually not handled. Reported-by:

Add support for the .get_selection() pad operation to the ov5670 sensor driver. Report the native sensor size (pixel array), the crop bounds (readable pixel array area) and the current and default analog crop rectangles. Currently all driver's modes use an analog crop rectangle of size [12, 4, 2600, 1952]. Instead of hardcoding the value in the operation implementation, ad an .analog_crop field to the sensor's modes definitions, to make sure that if any mode gets added, its crop rectangle will be defined as well. While at it re-sort the modes' field definition order to match the declaration order and initialize the crop rectangle in init_cfg().

The sensor has 2592*1944 active pixels, surrounded by 16 active dummy pixels and there are an additional 24 black rows "at the bottom".

There are currently two modes supported by this driver: 2592*1944 and 1296*972. The second mode is obtained thanks to subsampling while keeping the same field of view (FoV). No cropping involved, hence the harcoded values. Signed-off-by:Quentin Schulz <quentin.schulz@theobroma-systems.com> Reviewed-by:

2x2 binning works fine for RAW10 capture, but for RAW8 1232p mode it leads to corrupted frames [1][2]. Using the special 2x2 analog binning mode fixes the issue, but causes artefacts for RAW10 1232p capture. So here we choose the binning mode depending upon the frame format selected. As both binning modes work fine for 480p RAW8 and RAW10 capture, it can share the same code path as 1232p for selecting binning mode.

Gain control is badly documented in publicly available (including leaked) documentation. There is an AGC pre-gain in register 0x3a13, expressed as a 6-bit value (plus an enable bit in bit 6). The driver hardcodes it to 0x43, which one application note states is equal to x1.047. The documentation also states that 0x40 is equel to x1.000. The pre-gain thus seems to be expressed as in 1/64 increments, and thus ranges from x1.00 to x1.984. What the pre-gain does is however unspecified. There is then an AGC gain limit, in registers 0x3a18 and 0x3a19, expressed as a 10-bit "real gain format" value. One application note sets it to 0x00f8 and states it is equal to x15.5, so it appears to be expressed in 1/16 increments, up to x63.9375. The manual gain is stored in registers 0x350a and 0x350b, also as a 10-bit "real gain format" value. It is documented in the application note as a Q6.4 values, up to x63.9375. One version of the datasheet indicates that the sensor supports a digital gain: The OV5640 supports 1/2/4 digital gain. Normally, the gain is controlled automatically by the automatic gain control (AGC) block. It isn't clear how that would be controlled manually. There appears to be no indication regarding whether the gain controlled through registers 0x350a and 0x350b is an analogue gain only or also includes digital gain. The words "real gain" don't necessarily mean "combined analogue and digital gains". Some OmniVision sensors (such as the OV8858) are documented as supoprting different formats for the gain values, selectable through a register bit, and they are called "real gain format" and "sensor gain format". For that sensor, we have (one of) the gain registers documented as 0x3503[2]=0, gain[7:0] is real gain format, where low 4 bits are fraction bits, for example, 0x10 is 1x gain, 0x28 is 2.5x gain If 0x3503[2]=1, gain[7:0] is sensor gain format, gain[7:4] is coarse gain, 00000: 1x, 00001: 2x, 00011: 4x, 00111: 8x, gain[7] is 1, gain[3:0] is fine gain. For example, 0x10 is 1x gain, 0x30 is 2x gain, 0x70 is 4x gain (The second part of the text makes little sense) "Real gain" may thus refer to the combination of the coarse and fine analogue gains as a single value. The OV5640 0x350a and 0x350b registers thus appear to control analogue gain. The driver incorrectly uses V4L2_CID_GAIN as V4L2 has a specific control for analogue gain, V4L2_CID_ANALOGUE_GAIN. Use it. If registers 0x350a and 0x350b are later found to control digital gain as well, the driver could then restrict the range of the analogue gain control value to lower than x64 and add a separate digital gain control.
