Message-ID: <20201129114148.13772-8-cezary.rojewski at intel.com>
From: Mateusz Gorski <mateusz.gorski at linux.intel.com>
commit 1b450791d517d4d6666ab9ab6d9a20c8819e3572 upstream.
For pipes supporting multiple input/output formats, kcontrol is
created and selection of pipe input and output configuration
is done based on control set.
If more than one configuration is supported, then this patch
allows user to select configuration of choice
using amixer settings.
