The return value from abs() for the most negative integer is
undefined. Cap it properly for the 32bit sample handling.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
The handling of 16bit samples in the peak calculations has a bug when
a sample with 0x8000 is passed. As abs() treats 32bit int, it returns
0x8000. And yet the code stores back into 16bit value again.
To fix that overflow, use 32bit value (i.e. val instead of sval) for
the further calculations.

In Linux 5.14, a new feedback mechanism for USB Audio
Gadget is introduced (commit e89bb428), along with a
new control element "Capture Pitch 1000000". This patch
adds support for this feature. Note that this property
seems to be the reverse of PCM Rate Shift, so we have
to take reciprocal of pitch.

An object can be declared within a class definition as follows:
Class.Pipeline.volume-playback {
Object.Widget.pga.0 {
ramp_step_ms 250
}
}
While instantiating the volume-pipeline class, the pga object
could be modified as follows:
Object.Pipeline.volume-playback.0 {
Object.Widget.pga.0 {
format "s24le"
}
}
When building the pga.0 object in the class definition, merge
the attributes declared in the volume-playback.0 object to create
a new config as follows to make sure that all attributes are
set for the pga object.
Object.Widget.pga.0 {
ramp_step_ms 250
format "s24le"
}

Some objects just need tobe processed to add their attributes
to the private data section of their parent objects.
An example of this would be the pdm_config objects for
DMIC DAI's. Each pdm_config object's attributes need
to be added as separate arrays in the DAI object's
private data.
Modify the signature of tplg_add_object_data() to pass
the array_name parameter when multiple objects of the
same type in the same parent are processed.

Classes definitions in Topology2.0 can have attributes
qualified with the "automatic" constraint. Values for
these attributes will be calculated by the compiler.
This patch provides a generic method for defining automatic
attributes computation logic for different classes.
To update automatic attributes for a class, add an item
in object_build_map with auto_attr_updater defined, and then
add updating logic in the custom auto_attr_updater function.

Object.Base.channel."fr" {

Object.Base.ops."ctl" {

#256 binds the mixer control to volume get/put handlers
get 256
put 256

and pga class embeds the mixer objects as follows:
Class.Widget."pga" {

Object.Control {
mixer."0" {...}
mixer."1" {...}
}
The pre-processor starts with the top-pevel PGA widget object
and processes the mixer objects in the class definition.
This will recursively pre-processes its child objects to add the channels,
tlv and ops.
