2186fe21e5 ALSA: hda/realtek: Autodetect Cirrus Logic companion amplifier bindings
We do not need model specific HDA quirks to construct the component
binding details of Cirrus Logic companion amplifiers as this information
is already present in the ACPI.

Quirks are then only required for special workarounds not described in
the ACPI such as internal configuration of the Realtek codecs.

The codec pointer is now initialized in hda_component_manager_init() so
that we can detect when companion amplifiers are found in the ACPI but
the SSID invokes a quirk that also attempts to create the component
binding.

28b329f431 ALSA: hda: hda_component: Fix mutex crash if nothing ever binds
Move the initialization of parent->mutex into
hda_component_manager_init() so that it is always valid.

In hda_component_manager_bind() do not clear the parent information.
Only zero-fill the per-component data ready for it to be filled in
by the components as they bind.

Previously parent->mutex was being initialized only in
hda_component_manager_bind(). This meant that it was only
initialized if all components appeared and there was a bind callback.
If there wasn't a bind the mutex object was not valid when the
Realtek driver called any of the other functions.

047b9cbbaa ALSA: hda: hda_component: Protect shared data with a mutex
The hda_component contains information shared from the amp drivers to
the codec that can be altered (for example as the driver unloads). Guard
the update and use of these to prevent use of stale data.

3b2a858287 ALSA: hda: hda_component: Move codec field into the parent
There is one codec shared across all of the bound HDA components and a
copy is usually stashed in the amp driver so it doesn't need to be in
every hda_component.

1adf91011f ALSA: hda: hda_component: Change codecs to use component parent structure
Change the hda_component binding APIs to pass the hds_component_parent
as the parameter so the array of components can be abstracted.

960ccf6eaf ALSA: hda: hda_component: Introduce component parent structure
In preparation for moving duplicated members from the hda_component
structure introduce a parent structure that wraps the array of
components. This also allows us to confine the knowledge of the maximum
number of entries to the hda_component files and eliminate passing that
redundant information around and making direct accesses to the array.

ec6f32bc92 ALSA: hda: hda_component: Initialize shared data during bind callback
Move the initialization of the shared struct hda_component array into
hda_component_manager_bind().

The purpose of the manager bind() callback is to allow it to perform
initialization before binding in the component drivers. This is the
correct place to initialize the shared data.

The original implementation initialized the shared data in
hda_component_manager_init(). This is only done once during probe()
of the manager driver. So if the component binding was unbound and
then rebound, the shared data would not be re-initialized.

fd895a74dc ALSA: hda: realtek: Move hda_component implementation to module
Move the generic parts of the hda_component implementation into a new
hda_component module. This will allow other HDA codecs to add support
for the component binding API without duplicating all the code.
