This small series aims at reducing rkisp1 startup flicker due to
suboptimal defaults and the lack of coordination between the pipeline
handler and the AGC algorithm.

Changes in v2:
- set default exposure to maximum frame duration
- use exposure/gain from activeState in setControls()

Mikhail Rudenko (4):
  ipa: rkisp1: agc: Use better defaults for analogue gain and exposure
  utils: ipc: Allow start method with output parameters in IPA proxies
  rkisp1: synchronize sensor controls with IPA
  ipa: rkisp1: use active state in setControls
