This series introduces dynamic pinctrl and adds support for the SOF on the mt8188-mt6359 machine driver.

Changes since v2: - revise mtk_sof_check_tplg_be_dai_link_fixup().

Changes since v1: - minor changes to incorporate the suggestions from the reviewer.

New subject: [PATCH v3 1/3] ASoC: mediatek: mt8188-mt6359: support dynamic pinctrl

To avoid power leakage, it is recommended to replace the default pinctrl state with dynamic pinctrl since certain audio pinmux functions can remain in a HIGH state even when audio is disabled. Linking pinctrl with DAPM using SND_SOC_DAPM_PINCTRL will ensure that audio pins remain in GPIO mode by default and only switch to an audio function when necessary.

New subject: [PATCH v3 2/3] ASoC: mediatek: common: revise SOF common code

Originally, normal dai link fixup callback is overwritten by sof fixup callback on mtk_sof_card_late_probe and it relies on the mapping defined on struct sof_conn_stream.

It's not flexible. When a new hardware connection is adopted, user needs to update struct sof_conn_stream defined in machine driver which is used to specify the mapping relationship of normal BE and SOF BE.

In the patch, mtk_sof_check_tplg_be_dai_link_fixup() is introduced for all normal BEs. In mtk_sof_late_probe, back up normal BE fixup if it exists and then overwrite be_hw_params_fixup by the new callback.

There are two cases for FE and BE connection.

case 1: SOF FE -> normal BE -> SOF_BE

case 2: normal FE -> normal BE

In the new fixup callback, it tries to find SOF_BE which connects to the same FE, and then reuses the fixup of SOF_BE. If no SOF_BE exists, it must be case 2, so rollback to the original fixup if it exists.

As a result, the predefined relation is not needed anymore. Hardware connection can be controlled by the mixer control for AFE interconn. Then, DPCM finds the BE mapping at runtime.

New subject: [PATCH v3 3/3] ASoC: mediatek: mt8188-mt6359: add SOF support

SOF is enabled when adsp phandle is assigned to "mediatek,adsp". The required callback will be assigned when SOF is enabled.

Additionally, "mediatek,dai-link" is introduced to decide the supported dai links for a project, so user can reuse the machine driver regardless of dai link combination.
