From d577cf76fa3192f9e656bb101aa54d25a6a71347 Mon Sep 17 00:00:00 2001 From: Kai Vehmanen Date: Fri, 15 Nov 2019 14:44:47 +0200 Subject: ALSA: hda: hdmi - fix port numbering for ICL and TGL platforms Semantics of port#0 differ between ICL and TGL: ICL port#0 -> never used for HDAudio ICL port#1 -> should be mapped to first pin (0x04) TGL port#0 -> typically not used, but HW has the support, so should be mapped to first pin (0x04) TGL port#1 -> should be mapped to 2nd pin (0x06) Refactor the port mapping logic to allow to take the above differences into account. Fixes issues with HDAudio on some TGL platforms.
