Re: [PATCH 4.19 003/206] ASoC: tegra: tegra_wm8903: Support nvidia, headset property

Hi!

[ Upstream commit 3ef9d5073b552d56bd6daf2af1e89b7e8d4df183 ]

The microphone-jack state needs to be masked in a case of a 4-pin jack when microphone and ground pins are shorted. Presence of nvidia,headset tells that WM8903 CODEC driver should mask microphone's status if short circuit is detected, i.e headphones are inserted.

• if (of_property_read_bool(card->dev->of_node, "nvidia,headset"))

• shrt = SND_JACK_MICROPHONE;
  

This property is not properly documented, not it is used anywhere.

Best regards, Pavel
