This patch series adds support for Texas Instruments TAC5XX2 family of
SoundWire smart amplifiers, including TAC5572, TAC5672, TAC5682, and
TAS2883 devices.

The series includes:
- SDCA power state management helper for PDE verification
- New codec driver for TAC5XX2 family with SmartAmp, SmartMic,
UAJ, and HID support
- Machine driver integration for Intel SoundWire platforms
- ACPI match entries for Intel MTL platform

Changes in v15: (Patch 2/4)
- call pm_runtime_resume instead of waiting for
device to get initialised similar to other drivers
- skip reading the uaj and hid registers in the interrupt
handler if the uaj is not supported
- remove had_unattached in the dev_resume callback
- detect headset in the dev_resume callback only if the uaj
is supported
- indentation fixes to use reverse-xmas tree

Changes in v14:
- Resending complete series (v13 1/4 was accidentally sent alone)
- rename the first_hw_init to first_hw_init_done for readability.
- Removed dummy tac5xx2_sdw_clk_stop function (Patch 2/4)
- Added pm_runtime calls in .set_jack callback (Patch 2/4)
- Improved error handling for early .set_jack calls (Patch 2/4)
- drop uaj_lock to make it simiar to other drivers (Patch 2/4)
- move the pm_runtime_enable to probe and keep only
pm_runtime_set_active for first attach case. (Patch 2/4)
- remove tac5xx2_sdw_clk_stop as currently it is dummy (Patch 2/4)
- Used xmas tree style in .hw_free (Patch 2/4)

Changes in v13:
- no code changes (v13 1/4 was sent alone accidentally)

Changes in v12:
- Used correct namespace while exporting variables (Patch 1/4)
- Fixed missing entity information in logging (Patch 1/4)
- Removed hw_init check in .set_jack (Patch 2/4)
- Added missing pm_runtime_disable in .remove callback (Patch 2/4)
- Improved error logging in .hw_params and .hw_free (Patch 2/4)
- Included part_id in firmware binary name (Patch 2/4)
- Updated firmware header parsing (Patch 2/4)
