Subject: [PATCH] ASoC: tegra: tegra_wm8903: Support nvidia, headset property
Git-commit: 3ef9d5073b552d56bd6daf2af1e89b7e8d4df183
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518
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.
