From bff03e81502cb9ac99daeeb47b4d0e779cc48fde Mon Sep 17 00:00:00 2001 From: John Hsu Date: Wed, 6 Jul 2016 10:09:35 +0800 Subject: ASoC: nau8825: jack connection decision with different insertion logic The original design only covers the jack insertion logic is active low. Add more condition to cover no matter the logic is active low and high.
