2024-04-16ASoC: mediatek: Add common snd_soc_ops .startup() callbackAngeloGioacchino Del Regno
MediaTek platforms are typically setting PCM rate and channels constraints for playback, capture and HDMI/DisplayPort playback: commonize the startup callback by adding the PCM constraints data to the mtk_platform_card_data structure and by reusing the common mtk_soundcard_startup() function for all of them by getting back the parameters from the aforementioned struct.

2024-04-16ASoC: mediatek: Add common machine soundcard driver probe mechanismAngeloGioacchino Del Regno
Add a common machine soundcard driver probe function that supports both DSP and AFE-direct usecases and also provides a hook for legacy machine soundcard driver probe mechanisms. Note that the hook is there because, even for legacy probe, a lot of the actual code can still be commonized, hence still reducing duplication for the legacy devicetree retrocompatibility cases. This common probe function deprecates all of the inconsistent previous probe mechanisms and aims to settle all of the MediaTek card drivers on consistent and common devicetree properties describing wanted DAIs, device specific DAI configuration and DAI links to codecs found on each device/board.

2024-03-25ASoC: mediatek: Assign dummy when codec not specified for a DAI linkAngeloGioacchino Del Regno
MediaTek sound card drivers are checking whether a DAI link is present and used on a board to assign the correct parameters and this is done by checking the codec DAI names at probe time. If no real codec is present, assign the dummy codec to the DAI link to avoid NULL pointer during string comparison.

2023-06-02ASoC: mediatek: common: soundcard driver add dai_fmt supportTrevor Wu
There are two changes included in the patch. First, add set_dailink_daifmt() function, so dai_fmt can be updated by the configuration in dai-link sub node. Second, remove codec phandle from required property in dai-link sub node. For example, user possibly needs to update dai-format for all etdm co-clock dai-links, but codec doesn't need to be specified in capture dai-link for a speaker amp.

Add missing of_node_put()s before the returns to balance of_node_get()s and of_node_put()s, which may get unbalanced in case the for loop 'for_each_available_child_of_node' returns early.
