[PATCH v2 0/3] Allow retrieving accessory detection reference on MT8188

[Nícolas F. R. A. Prado]

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
3 updates the MT8188-MT6359 sound driver to register the audio jack and
initialize the ACCDET driver for detection, if the property is present.

Tested on the Genio 700 EVK board.

  the property should only be present if the accdet is actually used
