From eb0b8481c2e03a5ae01f6bea60b42109bd12b6fe Mon Sep 17 00:00:00 2001 From: Svyatoslav Ryhel Date: Wed, 8 Mar 2023 09:34:56 +0200 Subject: [PATCH] ASoC: tegra: Support coupled mic-hp detection This quirk is used for cases when there is GPIO which detects any type of 3.5 Jack insertion and actual type of jack is defined by other GPIO. 3.5 Jack GPIO generates interrupt and MIC GPIO indicates type of Jack only if 3.5 Jack GPIO is active.
