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 v3 series is based on linux_media master. This work addresses Mauro and Takashi's comments on Patch v2 series.
Changes since Patch v2 series: - Added documentation for uapi and new MC interfaces 1. Ran make for documentation and Mauro's doc script. Thanks for sharing the script. - Updated commit logs as needed for clarity. - media: v4l-core add enable/disable source common interfaces Addressed comments - added static inlines in header file - media: dvb-frontend invoke enable/disable_source handlers Moved the patch after enable/disable handlers and left pipe in dvb_frontend_private - media: au0828 video remove au0828_enable_analog_tuner() and media: au0828 video change to use v4l_enable_media_source() 1. Collapsed these two patches - it doesn't make sense to keep them separate. Also added FIXME as per Mauro's suggestion. - media: au0828 change to use Managed Media Controller API 1. Added comment explaining the need for using udev->product instead of dev->board.name - media: au0828 add enable, disable source handlers 1. Changed to handle S-Video and Composite inputs. 2. Fixed a bug that lets Video in when ALSA holds the source. 3. Added comments to one FIXME for s_input changes. Fix is in progress and will send it in a day or two combined with other issues found in au0828 video in the way it handles input. Doesn't impact this routine, changes are all in au0828-video. - sound/usb: Use Media Controller API to share media resources 1. Addressed comments from Mauro and Takashi about void pointer use. 2. Fixed kbuildbot error when MEDIA_SUPPORT=m - Dropped media: Ensure media device unregister is done only once Device removal worked without any changes to media unregister path. This work isn't necessary.
