The IPAIPU3 interface currently uses event-type based structures in order to communicate with the pipeline-handler (and vice-versa). Replace the event based structures with dedicated functions associated to each operation. The translated naming scheme of actions to signals are: ActionSetSensorControls => setSensorControls ActionParamFilled => paramsBufferReady ActionMetadataReady => metadataReady The translated naming scheme of events to dedicated functions are: EventProcessControls => queueRequest() EventStatReady => processStatsBuffer() EventFillParams => fillParamsBuffer() The dedicated functions are called from pipeline-handler to the IPA using IPC. These functions run asynchronously and when completed, the IPA emits the respective signals as stated above in the translated naming scheme. The EventProcessControls is translated to queueRequest() to bring symmetry to the IPU3 interface with other IPA interfaces.

2022-04-07test: v4l2_videodevice: Fix format configuration in the vimc pipelineLaurent Pinchart
The V4L2VideoDeviceTest class configures the capture pipeline with parameters that are partly hardcoded, and partly come from the current configuration of the device. In particular, with the vimc pipeline, the sensor subdevice is configured with the size retrieved from the capture video node, and the video node is then reconfigured to 640x480. Relying on the current (and thus possibly random) device configuration can lead to broken pipes when starting streaming. This currently causes failures of the dequeue_watchdog test when run after the formats test. Fix it by explicitly setting the same size for both the vimc subdevs and the video capture device.

2022-04-01libipa: camera_sensor_helper: Implement exponential gain modelLaurent Pinchart
The CameraSensorHelper specifies two gain models, linear and exponential. They are modelled after the MIPI CCS specification. Only the linear model has been implemented, the exponential model was left for later. We now need to support sensors that configure their gain in a hardware register with a value expressed in dB. This has similarities with the MIPI CCS exponential gain model, but is only has an exponential factor, while CCS also allows sensors to support a configurable linear factor. The full CCS exponential model needs two values (for the linear and exponential factors) to express a gain, while IPAs use a single linear gain value internally. However, the exponential gain model example in the CCS specification has a fixed linear factor, which may indicate that it could be common for sensors that implement the exponential gain model to only use the exponential factor. For this reason, implement the exponential gain model with a fixed linear factor, but with a sensor-specific coefficient for the exponential factor that allows expressing the gain in dB (or other logarithmical units) instead of limiting it to powers of 2 as in the MIPI CCS specification.
