From 88faae2c2e35c88a806c052a7fc20948211b0895 Mon Sep 17 00:00:00 2001 From: Ian W MORRISON Date: Thu, 31 Aug 2017 08:35:47 +1000 Subject: [PATCH] ASoC: rt5645: Add jack detection workaround for MINIX Z83-4 based devices The MINIX NEO Z83-4 and MINIX NEO Z83-4 Pro devices requires jd_mode=3 to make the jack detection work. Using a BIOS DMI product of "Z83-4" will match both devices of 'NEO Z83-4' and 'Z83-4 Pro'.
