* adv7481: Add support for interlaced HDMI and CVBS inputSuprith Malligere Shankaregowda2018-06-08
| | | | | | | | | | Set active lines based on input standard returned by SD core. Add vid parameter to sd_timings to return number of active lines to user. Increase SDP_NUM_TRIES to lock stable input. Return v4l2_field type of HDMI and CVBS INPUT to userspace.

* msm: BA: Create Bridge Abstraction (BA)Domi Papoi2017-06-08
Create bridge abstraction driver to provide a framework that can be used to abstract different types of bridge chips under a common API. The framework also allows multiple drivers to control different functional aspects of a bridge chip. The bridge abstraction driver is limited to bridge chips that deal with converting audio/video data from one protocol to a different one.
