The new helper matches perfectly the RPi implementation and can therefore replace the pipeline specific implementation. There are slight changes in the API of the two but noting preventing it to be a drop in replacement. The major new addition to the DelayedControls implementation is the ability to queue controls a hard of time. This allows the concept of pipeline depth we already have for buffers to be extended to controls. Patch 1/8 adds the new core helper and its unit test. Patch 2/8 and 3/8 replaces StaggerdCtrl with DelayedControls in the Raspberry Pi pipeline handler. Patch 4/8 adds an interface based on DelayedControls to CameraSensor. And last 5/8 - 8/8 make use of the new helper in the RkISP1 pipeline to completely remove another local helper (Timeline). The RkISP1 IPA feels much snappier after this change but this is anecdotal and no real measurements have been done as the RkISP1 IPA at this stage is neither advanced nor tuned.
