Subject: ASoC: arizona: Add support for multiplexer with no associated mixer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=17bd09e5457740425fee6ca2bb685a2a55c12c18;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ASoC: arizona: Add support for multiplexer with no associated mixer

The Asynchronous Sample Rate Converters on the wm5102/wm5110 have no
mixer attached to their input, but they do allow the input to be
selected from a number of sources via a multiplexer. Currently the
platform assumes the presence of 4 multiplexers and a mixer for each
block.

This patch adds support multiplexed single input blocks into the Arizona
platform.
