2021-08-05ipa: raspberrypi: AGC: handle modes with different sensitivitiesDavid Plowman
When the sensor is switched to a mode with a different sensitivity, the target exposure values need to be adjusted proportionately to maintain the same image brightness.

This commit adds a tuning file for the 12MP imx378 sensor. The sensor actually shares the same driver (and CamHelper) as the imx477 so only a new tuning file is required. The default choice of imx477.json can be overridden by pointing LIBCAMERA_RPI_TUNING_FILE at a version of the new imx378.json file.

Extend the CameraSensorHelper factory with support for the IMX258 sensor found in the Nautilus Chromebook. The values are read by manually tweaking the IMX258 kernel driver. The IMX258 kernel driver hints that the sensor may be compatible with the MIPI CCS specification, as the register set matches. The values for analog gain constants are obtained by reading the register indexes, corresponding to the analog gain constants, as mentioned in MIPI CCS v1.1 specification. The values have further been confirmed by Dave Stevenson as being those specified in the datasheet.

2021-07-12ipa: raspberrypi: Allow long exposure modes for imx477.Naushir Patuck
Update the imx477 CamHelper to use long exposure modes if needed. This is done by overloading the CamHelper::GetVBlanking function to return a frame length (and vblank value) computed using a scaling factor when the value would be larger than what the sensor register could otherwise hold. CamHelperImx477::Prepare is also overloaded to ensure that the "device.status" metadata returns the right value if the long exposure scaling factor is used. The scaling factor is unfortunately not returned back in metadata. With the current imx477 driver, we can achieve a maximum exposure time of approx 127 seconds since the HBLANK control is read-only.

2021-06-28ipa: Create a camera sensor helper classJean-Michel Hautbois
For various sensor operations, it may be needed to do sensor specific computations, like analogue gain or vertical blanking. This commit introduces a new camera sensor helper in libipa which aims to solve this specific issue. It is based on the MIPI alliance Specification for Camera Command Set and implements, for now, only the analogue "Global gain" mode. Setting analogue gain for a specific sensor is not a straightforward operation, as one needs to know how the gain is calculated for it. Three helpers are created in this patch: imx219, ov5670 and ov5693. Adding a new sensor is pretty straightforward as one only needs to implement the sub-class for it and register that class to the CameraSensorHelperFactory.

2021-06-08ipa: ipu3: Calculate line duration from IPACameraSensorInfoUmang Jain
Squash \todo by calculating line duration from IPACameraSensorInfo, now passed in, to IPU3Agc::initialise(). Since line duration is now calculated from real values, store it as a private member in IPU3Agc class. As a further step, replace the associated global constant, kMaxExposureTime, with a private IPU3Agc class member as well, and assign its value correspondingly in IPU3Agc::initialise(), similar to previous precedence.

A custom gamma LUT is used, but the table is not calculated at startup, resulting in an all 0's frame. Use the drfault LUT specified in the Linux kernel as a first estimation.

2021-05-27controls: Split FrameDurations into FrameDuration and FrameDurationLimitsPaul Elder
We need a separate control to report the nominal frame duration, but it's also useful to report the min/max frame duration values that will be used. Split the FrameDurations control into FrameDuration and FrameDurationLimits respectively to support both of these.
