ipa: rkisp1: Support raw capture in IPA operations
The RkISP1 can capture raw frames by bypassing the ISP. In that mode,
the ISP will not produce statistics nor consume parameters. Most
algorithms will thus be unable to run, with one exception: the AGC will
still be able to configure the sensor exposure time and analog gain in
manual mode.
To prepare for this, add the ability to disable algorithms for the
duration of the capture session based on the camera configuration.
Individual algorithms report whether they support raw formats at
construction time, and the IPA module disables algorithms in configure()
based on the stream configurations.
Disabled algorithms are skipped during the capture session in the
processStatsBuffer() operation. As the ISP doesn't produce statistics,
don't try to access the stats buffer. There is no need for similar logic
in fillParamsBuffer() as that operation won't be called for raw capture.
All algorithms report not supporting raw capture by default. Raw support
in AGC will be added separately.
The feature is implemented in the RkISP1 module without any support from
libipa at this point to avoid designing a generic API based on a single
user. This may be changed in the future.
