2019-10-11libcamera: ipa: rkisp1: Add basic control of auto exposureNiklas Söderlund
Add an IPA which controls the exposure time and analog gain for a sensor connected to the rkisp1 pipeline. The IPA supports turning AE on and off and informing the camera of the status of the AE control loop.

2019-10-11libcamera: ipa: Extend to support IPA interactionsNiklas Söderlund
The IPA interface needs to support interactions with the pipeline; add interfaces to control the sensor and handling of request ISP parameters and statistics.

2019-10-08ipa: vimc: Add support for tracing operationsJacopo Mondi
Add support to the dummy VIMC IPA for tracing operation by using a FIFO channel that will be used by the IPA Interface test to verify communications with the IPA. At the moment only add support for the init() operation as it's the only defined one. Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>
2019-09-15libcamera: Move ipa includes to the same level as libcameraLaurent Pinchart
The ipa includes are located in include/libcamera/ipa/. This gives an incorrect impression that they are a sub-part of the rest of the libcamera API, while they are the API towards the IPA the same way that include/libcamera/ contains the API towards applications. To clarify this, move them to include/ipa/. The IPA headers are however still part of libcamera, so installing them to ${prefix}/include/ipa/ would make little sense. To fix this, move the application facing API to ${prefix}/include/libcamera/libcamera/ when installed, and the IPA to ${prefix}/include/libcamera/ipa/. When major versions of libcamera will be released, they could then be installed side by side in ${prefix}/include/libcamera-${version}/.
