Subject: [PATCH 0/6] Add audio support in v4l2 framework
Date:   Thu, 29 Jun 2023 09:37:47 +0800
Message-Id: <1688002673-28493-1-git-send-email-shengjiu.wang@nxp.com>
Precedence: bulk

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
