2020-10-26libcamera: control_ids: Define draft controlsJacopo Mondi
libcamera is in the process of defining its own set of controls to enable applications to control the image capture process and return information on the captured frames. To temporarily close the gap in the Android camera HAL and support all controls required in the LIMITED hardware level, define a set of Draft controls whose values are taken from their Android definition, in order to allow pipeline handlers to support Android.

2020-10-26libcamera: Support draft controls and propertiesKieran Bingham
Extend the control and property framework to support exposing draft controls and properties in a scoped namespace. The controls/properties themselves will retain the same ordering in the relevant enum/id maps - but the access to any draft control will require explicitly referencing through its' draft:: namespace prefix.

2020-10-26libcamera: controls: Disable ControlValue<T> construction from unsupported TLaurent Pinchart
The ControlValue<T> constructor for non-array values is a template function that participates in overload resolution for all T types that are not Span or std::string. Other T types that are not supported then result in a compilation error. This causes issues when calling an overloaded function that can accept both a ControlValue and a Span with an std::array<U> parameter. The first overload will be resolved using implicit construction of a ControlValue from the std::array<U>, while the second overload will be resolved using implicit construction of a Span<U> from the std::array<U>. This results in a compilation error due to an ambiguous function call. The first overload is invalid, selecting it would result in a compilation error in the ControlValue constructor, as the ControlValue<T> constructor doesn't support std::array<U> for type T. The compiler can't know about that, as overload resolution happens earlier. To fix it, we can disable the ControlValue<T> constructor for unsupported types T, moving the type check from compilation of the function to overload resolution. The constructor will not participate in overload resolution, and the call won't be ambiguous. The end result is the same for unsupported types, compilation will fail.

2020-10-21libcamera: pipeline: Fail match() when no camera is registeredLaurent Pinchart
The rkisp1 and simple pipeline handlers can fail to register any camera, if initialization of all the detected cameras fail. In that case, they still return success from their match function. As no camera gets registered, the pipeline handler is immediately destroyed, releasing the acquired media devices, and the camera manager immediately tries to match the same pipeline handler with the same media device, causing an endless loop. Fix it by returning false from the match function if no camera gets registered.
