Subject: [PATCH 0/6] Add audio support in v4l2 framework

Audio signal processing has the requirement for memory to
memory similar as Video.

This patch is to add this support in v4l2 framework, defined
new buffer type V4L2_BUF_TYPE_AUDIO_CAPTURE and
V4L2_BUF_TYPE_AUDIO_OUTPUT, defined new format v4l2_audio_format
for audio case usage.

The created audio device is named "/dev/audioX".

And add memory to memory support for two kinds of i.MX ASRC
module
