[PATCH v8 00/10] ASoC: mediatek: Add support for MT8196 SoC

[Cyril Chao <Cyril.Chao@mediatek.com>]

This series of patches adds support for Mediatek AFE of MT8196 SoC.
Patches are based on broonie tree "for-next" branch.

This v8 series is based on the v7 version posted by <darren.ye@mediatek.com>:
Link: <https://patchwork.kernel.org/project/alsa-devel/cover/20250822125301.12333-1-darren.ye@mediatek.com/>

Changes since v7:
  - Fix sparse warning in mt8196-nau8825 machine driver
    (reported by kernel test robot <lkp@intel.com>)
  - Reorder DT bindings patches before the driver patches so that the
    bindings land first and match the dependencies in the ASoC drivers
  - Replace the deprecated pcm_construct/pcm_destruct callbacks with
    pcm_new/pcm_free to follow the latest ASoC core API

Changes since v6:
 - optimize mtk_afe_pcm_pointer interface and improved logic checks.
 - update mt8196_afe_private structure by removing unused member variables.
 - only reference clocks directly supplied to afe and set required frequencies directly.
 - update adda driver according to reviewer suggestions.
 - update i2s driver according to reviewer suggestions.
 - update tdm driver according to reviewer suggestions.
 - optimize platform driver and update widget rotues.
 - move the sof route from platform driver to the machine driver, and moved pinctrl to platform driver.
 - update the afe yaml file to remove unnecessary clock references.

Changes since v5:
 - restore the commit message for mediatek,mt8196-afe.yaml and only remove the string document.
 - add reviewed owner for mediatek,mt8196-nau8825.yaml.
 - use SND_JACK_AVOUT as jack status.
 - use GENMASK_ULL to support 64-bit address masks.
 - modify the afe platform and i2s dai driver code based on reviewer's suggestions.

Changes since v4:
 - modify the mediatek,mt8196-afe.yaml commit message and add reviewed owner.
 - modify the mediatek,mt8196-nau8825.yaml commit message.
 - modify the audio common code based on reviewer's suggestions.
 - add reviewed and tested owners in the audio common code submission message.
 - fix cm update cnt calculation issue.

Changes since v3:
 - the AFE TOP CG index is added to the common header.
 - remove the audsys clk register and directly read and write to the regmap of afe cg clk.
 - modify the clk logic according to the suggestions.
 - remove the macro definition of MTKAIF4
 - remove the tdm cg event and directly read and write the tdm cg reg form the widget.
 - remove the i2s and cm cg event and directly read and write cg reg.
 - afe hopping and f26m clk cg are placed in remap_register_patch and enable.
 - the yaml file is modified according to the suggestions.
 - replace SND_SOC_DAIFMT_CBS_CFS with SND_SOC_DAIFMT_CBC_CFC.

Changes since v2:
  - remove the mtk_memif_set_channel interface modify.
  - remove duplicate definitions from the header file.
  - move the afe gate clk to the audio driver for management and registration
    and manage the afe clk gate in each dai driver.
  - delete the useless clk source.
  - the i2s driver adds i2s clk gate management, removes the additional dts
    configuration of i2s4.
  - the afe and i2s dai driver,memif and irq data structs are encapsulated using
    macros to reduce the amount of code.
  - the volatile reg is modified as suggested.
  - mt6681 codec is not supported, the mt6681 keyword is removed.
  - the name of the machine driver is changed from mt8196-mt6681.c to mt8196-nau8825.c
  - remove the i2s4 configuration from mt8196-afe.yaml and make the modifications as suggested.
  - change the mt8196-mt6681.yaml to mt8196-nau8825.yaml and make the modifications as suggested.

Changes since v1:
  - modify mtk_memif_set_channel and mtk_afe_pcm_pointer interfaces
    are improved to support mt8196.
  - remove duplicate definitions in the mt8196 common header file.
  - cm logic is merge into the afe platform driver.
  - modify afe clk to return judgment logic and remove useless clk sources.
  - refactor the mt8196 adda dai driver.
  - remove the gpio module and use SND_SOC_DAPM_PINCTRL to manage it.
  - removes CONNSYS_I2S related functions that are not supported in i2s dai driver.
  - fixed mt8196-afe.yaml and mt8196-mt6681.yaml syntax issues.
  - modify log printing in all modules.
  - optimize the header file included for machine driver.
