This series enables the MT8188-MT6359 sound driver to retrieve the MT6359 ACCDET sound component from a mediatek,accdet DT property, which allows detecting jack insertion/removal. Patch 1 describes the new property in the binding. Patch 2 implements the sound component retrieval in the common MTK soundcard driver. Patch 4 updates the MT8188-MT6359 sound driver to register the audio jack and initialize the ACCDET driver for detection, if the property is present. Patch 3 adds a stub to prevent a linker failure in case the MT6359-ACCDET config is disabled. Tested on the Genio 700 EVK board. Signed-off-by: Nícolas F. R. A. Prado <nfraprado@xxxxxxxxxxxxx> --- Changes in v3: - Removed the config select for CONFIG_SND_SOC_MT6359_ACCDET - Added patch 3 with stub for mt6359_accdet_enable_jack_detect() - Fixed return checks for mediatek,accdet handling to check for non-null rather than !IS_ERR(), and added error messages - Link to v2: https://lore.kernel.org/r/20250304-mt8188-accdet-v2-0-27f496c4aede@xxxxxxxxxxxxx Changes in v2: - Added CONFIG_SND_SOC_MT6359_ACCDET select in CONFIG_SND_SOC_MT8188_MT6359 to avoid build failure - Clarified in mediatek,accdet dt-binding and commit description that the property should only be present if the accdet is actually used - Link to v1: https://lore.kernel.org/r/20250214-mt8188-accdet-v1-0-6bbd5483855b@xxxxxxxxxxxxx --- Nícolas F.
