We want to perform remote audio auto test, need the audio jack to
change from plugout to plugin or vice versa by software ways.
Here the design is creating a sound-core root folder in the debugfs
dir, and each sound card will create a folder cardN under sound-core,
then the sound jack will create folders by jack_ctrl->ctrl->id.name,
and will create 2 file nodes jackin_inject and sw_inject_enable in
the folder, this is the layout of folder on a machine with 2 sound
cards:
$tree $debugfs_mount_dir/sound-core
sound-core/
├── card0
│ ├── HDMI!DP,pcm=10 Jack
│ │ ├── jackin_inject
│ │ └── sw_inject_enable
+ sound_core_debugfs_root = debugfs_create_dir("sound-core", NULL);
I would just use "sound" directory name here. Why "core" suffix?
OK, will change it to sound.
thx.
