2019-10-13libcamera: v4l2_device: Replace V4L2ControlList with ControlListLaurent Pinchart
The V4L2Device class uses V4L2ControlList as a controls container for the getControls() and setControls() operations. Having a distinct container from ControlList will makes the IPA API more complex, as it needs to explicitly transport both types of lists. This will become even more painful when implementing serialisation and deserialisation. To simplify the IPA API and ease the implementation of serialisation and deserialisation, replace usage of V4L2ControlList with ControlList in the V4L2Device (and thus CameraSensor) API. The V4L2ControlList class becomes a thin wrapper around ControlList that slightly simplifies the creation of control lists for V4L2 controls, and may be removed in the future.

2019-10-13libcamera: controls: Support accessing controls by numerical IDLaurent Pinchart
The ControlList class has template get() and set() methods to get and set control values. The methods require a reference to a Control instance, which is only available when calling them with a hardcoded control. In order to support usage of ControlList for V4L2 controls, as well as serialisation and deserialisation of ControlList, we need a way to get and set control values based on a control numerical ID. Add new contains(), get() and set() overload methods to do so. As this change prepares the ControlList to be used for other objects than camera, update its documentation accordingly.

2019-10-04libcamera: controls: Improve the API towards applicationsLaurent Pinchart
Rework the control-related classes to improve the API towards applications. The goal is to enable writing code similar to Request *req = ...; ControlList &controls = req->controls(); controls->set(controls::AwbEnable, false); controls->set(controls::ManualExposure, 1000); ... int32_t exposure = controls->get(controls::ManualExposure); with the get and set operations ensuring type safety for the control values. This is achieved by creating the following classes: - Control defines controls and is the main way to reference a control. It is a template class to allow methods using it to refer to the control type. - ControlId is the base class of Control. It stores the control ID, name and type, and can be used in contexts where a control needs to be referenced regardless of its type (for instance in lists of controls). This class replaces ControlIdentifier. - ControlValue is kept as-is. The ControlList class now exposes two template get() and set() methods that replace the operator[]. They ensure type safety by infering the value type from the Control reference that they receive. The main way to refer to a control is now through the Control class, and optionally through its base ControlId class. The ControlId enumeration is removed, replaced by a list of global Control instances. Numerical control IDs are turned into macros, and are still exposed as they are required to communicate with IPAs (especially to deserialise control lists). They should however not be used by applications. Auto-generation of header and source files is removed for now to keep the change simple. It will be added back in the future in a more elaborate form.

2019-08-19libcamera: camera_manager: Construct CameraManager instances manuallyLaurent Pinchart
The CameraManager class is not supposed to be instantiated multiple times, which led to a singleton implementation. This requires a global instance of the CameraManager, which is destroyed when the global destructors are executed. Relying on global instances causes issues with cleanup, as the order in which the global destructors are run can't be controlled. In particular, the Android camera HAL implementation ends up destroying the CameraHalManager after the CameraManager, which leads to use-after-free problems. To solve this, remove the CameraManager::instance() method and make the CameraManager class instantiable directly. Multiple instances are still not allowed, and this is enforced by storing the instance pointer internally to be checked when an instance is created.
