From: Stephen Warren Date: Wed, 1 Jun 2011 17:14:18 +0000 (-0600) Subject: ALSA: hda: Virtualize SPDIF out controls X-Git-Tag: firefly_0821_release~3680^2~4182^2~124^2~92 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=74b654c957e901e7596ebc7b9f5a1bea62b20509;p=firefly-linux-kernel-4.4.55.git ALSA: hda: Virtualize SPDIF out controls The SPDIF output controls apply to converter widgets. A future change will create a PCM device per pin widget, and hence a set of SPDIF output controls per pin widget, for certain HDMI codecs. To support this, we need the ability to virtualize the SPDIF output controls. Specifically: * Controls can be "unassigned" from real hardware when a converter is not used for the PCM the control was created for. * Control puts only write to hardware when they are assigned. * Controls can be "assigned" to real hardware when a converter is picked to support output for a particular PCM. * When a converter is assigned, the hardware is updated to the cached configuration.
