Add support for the Nuvoton NAU83G60 audio codec. The NAU83G60 is a
stereo 30W+30W smart amplifier with an integrated low-latency
Advanced Audio DSP.

Changes in v5:
- Add FW_LOADER to prevent silent probe failure
- Fix uninitialized return variables and add error checks for underlying I2C reads.
- Replace stack-allocated buffers in I2C transfers with heap-allocated memory.
- Eliminate potential Use-After-Free by synchronizing firmware loading.
- Protect PEQ memory control operations with mutex locks to ensure thread-safe register updates.
- Resolve TDM slot configuration races using mutex protection.
- Correct mathematically invalid TDM TX slot offsets during channel length changes.
- Ensure TDM streams are explicitly disabled when slots or slot_width is zero.
- Fix DSP protocol corruption due to missing locking in the DAPM clock event handler.
- Use FIELD_PREP() in protocol packing functions to replace manual bit-shifting.
- Replace deprecated of_property_count_strings() with device_property_read_string().
- Remove unnecessary CONFIG_ACPI ifdefs; struct acpi_device_id is available.
- Refactor repetitive DAPM event handlers (adacl/adacr/dacl/dacr).
- Simplify code flow by removing redundant gotos, variables, debug messages, and dev_get_platdata().
- Standardize driver style using switch-cases, positive logic checks, and reduced conditional nesting.
Changes in v4:
- Clean up unused DSP state flags (dsp_enable, dsp_created, dsp_fws_num).
- Fixed the use of an uninitialized stack variable (`status`).
- Fixed unhandled failures in `nau8360_dsp_init()` that caused duplicated
DAPM widgets to leak.
- Add mutex protection for PEQ memory and TDM slot caches.
- Restored the missing hardware memory access bit during suspend/resume
to prevent PEQ coefficients from being silently lost.
- Handled `regmap_read()` failure in `nau8360_vbat_level()` to prevent
the usage of uninitialized stack memory.
- Removed improper dynamic creation of DAPM widgets and routes within ALSA kcontrol
`put` handlers, using proper static instantiation instead.
- Moved RX enable logic to `startup()` for consistent stream state.
- Replaced synchronous `request_firmware()` with `request_firmware_nowait()`
to prevent deadlocks and avoid blocking the kernel during firmware I/O.
- Explicitly disable TDM RX/TX when slots or slot_width is zero.
Changes in v3:
- Add Kconfig and Makefile entries for the building system.
- Change block comments to C++ style.
- Add initialization for 'data_count' before usage.
- Fix a potential stack buffer overflow in DSP reply parsing by adding a strict 'data_count <= 0' check.
- Replace magic numbers with descriptive macros.
- Return -EBUSY in `nau8360_dac_mux_put_enum()` to prevent playback disruption.
- Remove the 'GFP_DMA' flag as DMA memory is not strictly required here.
- Convert multiple 'if' statements to 'switch' statements.
- Remove internal hardware debugging code for GPIO1 to GPIO3.
- Initialize TDM slot arrays to resolve `nau8360_set_tdm_slot()` setup failures.
- Fix event_missing and event_spurious in TDM/PEQ put functions.
- Fix uninitialized variable usage in TDM slot put.
- Add "Slot None" mapping with custom _get functions, and optimize I2C reads for this state.
- Refactor TDM slot validation into nau8360_validate_tdm_slots().
Changes in v2:
- Fixed nau8360_peq_coeff_put() to return 1 on value change.
- Refactored TDM slot routing to use ALSA kcontrols instead of custom masks in set_tdm_slot().
- Switched regmap cache type to REGCACHE_MAPLE.
- Dropped hardcoded DAC gain initialization to retain chip defaults.
- Used devm_snd_soc_register_component() for safe unregistration.
- Separated TDM TX/RX logic in shutdown() to safely support full-duplex operation.
- Refactored TDM enable/disable logic: moved RX enable from startup to hw_params,
TX enable from startup to set_tdm_slot, and handled disable logic in shutdown.
- Moved software/runtime configurations from DT properties to ALSA kcontrols (e.g., DSP bypass, low latency).
- Corrected supported PDM data length from 24 to 32 bits per datasheet specifications.
- Updated firmware DT property parsing to use standard firmware-name.
- Removed redundant VBAT bounds check in nau8360_sawtooth_params() as it is already validated by the caller.
- Read VBAT level dynamically via register instead of relying on a DT property.
- Cleaned up magic numbers by introducing PEQ band enumerations.
- Set dsp_fws_num to 0 to use default firmware paths if "firmware-name" is missing.
