This patch series updates ALSA driver, and au0828 core driver to use Managed Media controller API and Media Controller API to share media resource (tuner).
This Patch v2 series is based on linux_media master. This work addresses Mauro and Takashi's comments.
Composite or S-Video connector is the input case is still under discussion and isn't addressed in this series.
Patches 3 and 4 need documentation updates and will be sent later this week.
