2020-04-28libcamera: camera_sensor: Add method to get sensor infoJacopo Mondi
Add a method to retrieve the CameraSensorInfo to the CameraSensor class. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
2020-04-28libcamera: v4l2_subdevice: Add format informationJacopo Mondi
Define a map of static information associated with a media bus code. Start by reporting the bits-per-pixel for each media bus code defined by the V4L2 kernel API, to later expand it when necessary. Add to the V4L2SubdeviceFormat class a method to return the bits per pixel, retrieved by inspecting the static map of format information. While at it, remove a rogue map inclusion from header file.

The V4L2Device::getControls() function takes a ControlList that needs to be pre-populated with dummy entries for the controls that need to be read. This is a cumbersome API, especially when reading a single control. Make it nicer by passing the list of V4L2 controls as a vector of control IDs, and returning a ControlList.

2020-04-28libcamera: ipa_proxy: Provide suport for IPA configuration filesLaurent Pinchart
IPA modules may require configuration files, which may be stored in different locations in the file system. To standardize file locations between all IPAs and pipeline handlers, provide a helper function to locate a configuration file by searching in the following directories: - All directories specified in the LIBCAMERA_IPA_CONFIG_PATH environment variable ; or - In the source tree if libcamera is not installed ; otherwise - In standard system locations (etc and share directories). When stored in the source tree, configuration files shall be located in a 'data' subdirectory of their respective IPA directory. More locations, or extensions to the mechanism, may be implemented later.

Rename: ManualExposure -> ExposureTime ManualGain -> AnalogueGain Use micro-seconds units for ExposureTime. This is changed from milli- seconds. The latter would not allow very low exposure times. AnalogueGain switch to use a float to allow fractional gain adjustments. Update the uvcvideo pipeline handler to use the new exposure and gain units. For ExposureTime, UVC uses units of 100 micro-seconds, so map the values before setting V4L2_CID_EXPOSURE_ABSOLUTE. For AnalogueGain, UVC has no explicit gain units, so map the default gain value to 1.0 and linearly scale to the requested value.
