From 934e4885cb958566a34124e5a1dad2f9212a8ec6 Mon Sep 17 00:00:00 2001 From: Lori Hikichi Date: Thu, 28 Sep 2017 15:29:35 -0700 Subject: [PATCH] ASoC: cygnus: Remove support for 8 bit audio and for mono These modes of operation were not working properly and it is unclear if the hardware could fully support these modes properly. There is little to be gained by enabling these modes, therefore, we will just remove support.
