-Subject: ALSA: hda/hdmi - implement mst_no_extra_pcms flag
-
-From: Kai Vehmanen <kai.vehmanen@linux.intel.com>
-
-[ Upstream commit 2a2edfbbfee47947dd05f5860c66c0e80ee5e09d ]
-
-To support the DP-MST multiple streams via single connector feature,
-the HDMI driver was extended with the concept of backup PCMs. See
-commit 9152085defb6 ("ALSA: hda - add DP MST audio support").
-
-This implementation works fine with snd_hda_intel.c as PCM topology
-is fully managed within the single driver.
-
-When the HDA codec driver is used from ASoC components, the concept
-of backup PCMs no longer fits. For ASoC topologies, the physical
-HDMI converters are presented as backend DAIs and these should match
-with hardware capabilities. The ASoC topology may define arbitrary
-PCMs (i.e. frontend DAIs) and have processing elements before eventual
-routing to the HDMI BE DAIs. With backup PCMs, the link between
-FE and BE DAIs would become dynamic and change when monitors are
-(un)plugged. This would lead to modifying the topology every time
-hotplug events happen, which is not currently possible in ASoC and
-there does not seem to be any obvious benefits from this design.
-
-To overcome above problems and enable the HDMI driver to be used
-from ASoC, this patch adds a new mode (mst_no_extra_pcms flags) to
-patch_hdmi.c. In this mode, the codec driver does not assume
-the backup PCMs to be created.
