Enable headset jack detection for MT8188 platforms that use the MT6359
ACCDET block for it, indicated by the mediatek,accdet property in DT.
For those platforms, register a jack and initialize the ACCDET block to
report jack events through it.

Handle the optional mediatek,accdet property. When present, retrieve the
sound component from its phandle, so the machine sound driver can use it
to register the audio jack and initialize the MT6359 ACCDET for jack
detection.

Merge series from Ryan Walklin <ryan@testtoast.com>:
Hi All,
V3 of this patch adding headphone jack detection support to the Anbernic RGnnXX series of handhelds. V3 corrects my misunderstanding of derivation of ALSA UCM file paths, and adds recieved Reviewed-by and Tested-by tags. Thanks to those that have reviewed and fed back on previous versions.
Original message below:
This series adds the required device tree bindings to describe GPIOs for jack detection in the sun4i-codec driver, adds support for jack detection to the codec machine driver, and describes the hardware configuration in the RG35XX DTS. The existing speaker amplifier GPIO pin can then be used in concert with jack detection to enable userspace sound servers (via an ALSA UCM configuration) to disable the speaker route when headphones are connected.
Thanks to Chris Morgan for his assistance putting this series together.
Regards,
Ryan

Adding jack detection requires sound servers to act on the emitted
events, which are described by ALSA Use Case Manager configurations in
userspace. These configurations include the long card name in the file
path (falling back to card->name if this is not present), so add a long
card name for the H616 without spaces, making UCM referencing easier.

Add support for GPIO headphone detection with the hp-det-gpios
property. In order for this to properly disable the path upon
removal of headphones, the output must be labelled Headphone which
is a common sink in the driver.
Describe a headphone jack and detection GPIO in the driver, check for
a corresponding device tree node, and enable jack detection in a new
machine init function if described.

The previous H616 support patch added a single LINEOUT DAPM pin switch
to the card controls. As the codec in this SoC only has a single route,
this seemed reasonable at the time, however is redundant given the
existing DAPM codec widget definitions controlling the digital and
analog sides of the codec.
It is also insufficient to describe the scenario where separate
components (muxes, jack detection etc) are used to modify the audio
route external to the SoC. For example the Anbernic RG(##)XX series of
devices uses a headphone jack detection switch, GPIO-controlled speaker
amplifier and a passive external mux chip to route audio.
Remove the redundant LINEOUT card control, and add a Speaker pin switch
control and Headphone DAPM widget to allow control of the above
hardware.

Devices integrating Allwinner SoCs may use line-out or headphone jacks
with jack detection circuits attached to a GPIO. Support defining these
in DTs.
A number of Anbernic devices featuring the H700 SoC use this mechanism
to switch between a headphone jack and an internal speaker, so add these
to the allowed routing items.

The former code sets the V slot from inside set_bitwidth according to
the bitwidth of the PCM format. That's wrong, since:
* It overrides the V slot parsed from DT binding.
* The V slot is set shifted behind the I slot by the length of the PCM
bitwidth, but the PCM bitwidth has no assured relation to the TDM
slot width.
Replace the former logic by setting up the I/V sense transmission only
in case of both I/V slots being specified in devicetree, and never
override those values. In case the slots are left unspecified, disable
the transmission completely.
There's an improbable case someone is relying on the old behavior, but
if so, that's a setup that only works by accident, and cannot be sanely
supported going forward. There's no indication anyone is consuming the
I/V sense data up to today, so break the former behavior.

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:
ACE3 (Panther Lake) introduced support for microphone privacy feature which
can - in hardware - mute incoming audio data based on a state of a physical
switch.
The change in the privacy state is delivered through interface IP blocks
and can only be handled by the link owner.
In Intel platforms Soundwire is for example host owned, so the interrupt
can only be handled by the host.
Since the input stream is going to be muted by hardware, the host needs to
send a message to firmware about the change in privacy so it can execute a
fade out/in to enhance user experience.
The support for microphone privacy can be queried from the HW_CONFIG data
under the INTEL_MIC_PRIVACY_CAP tuple. This is Intel specific data, the
core will pass it to platform code if the intel_configure_mic_privacy()
callback is provided.
Platform code can call sof_ipc4_mic_privacy_state_change() to send the IPC
message to the firmware on state change.

Implement the three callbacks that is needed to enable support for
reporting the mic privacy change via soundwire.
In PTL the mic privacy reporting is supported via soundwire and DMIC and
the soundwire is owned by the host, it's interrupt is routed there.
To enable the interrupt, the sublink mask needs to be passed to the
multilink layer, the check_mic_privacy_irq/process_mic_privacy callbacks
needs to be implemented to check and report the mic privacy change.

New register has been introduced with PTL in the vendor specific SHIM
registers, outside of the IPs itself for microphone privacy status handling.
Via the PVCCS register the current microphone privacy status can be checked
and the interrupt generation on status change can be enabled/disabled.
The status change interrupt is routed to the owner of the interface
(DSP/host).
The PVCCS is provided for each sublink under the IP to make it possible to
control the interrupt generation per sublink.
On status change the MDSTSCHG bit needs to be cleared for all sublink of
the interface to be able to detect future changes in privacy.
The status bit (MDSTS) is volatile in all PVCCS register, it reflects the
current state of the GPIO signal.
Microphone privacy is a hardware feature (if enabled and configured that
way), the host has only passive, monitoring role.
The added functions are generic to be future proof if the mic privacy
support is extended beyond Soundwire and DMIC links.

ACE3 (Panther Lake) introduced support for microphone privacy feature which
can - in hardware - mute incoming audio data based on a state of a physical
switch.
The change in the privacy state is delivered through interface IP blocks
and can only be handled by the link owner.
In Intel platforms Soundwire is for example host owned, so the interrupt
can only be handled by the host.
Since the input stream is going to be muted by hardware, the host needs to
send a message to firmware about the change in privacy so it can execute a
fade out/in to enhance user experience.
The support for microphone privacy can be queried from the HW_CONFIG data
under the INTEL_MIC_PRIVACY_CAP tuple. This is Intel specific data, the
core will pass it to platform code if the intel_configure_mic_privacy()
callback is provided.
Platform code can call sof_ipc4_mic_privacy_state_change() to send the IPC
message to the firmware on state change.
