Keep HD-A support backward compatible with SOF v1.2 #264
SOF firmware v1.2 has no support for HD-A links. We need to assure latest kernel (SOF platform driver, machine drivers) can be configured to disable HD-A link support, to work with SOF 1.2 and topology w/o HD-A front & backends.
Humm, this is a bit vague. I am all for removing HDA/HDMI support with a config change, but
On what platforms do you want to ensure backwards compatibility? GLK selects HDAC_HDMI in the Kconfig
how would you deal with ABI changes that happened since 1.2?
how do we provide topologies that have no references to hda/hdmi? it's almost like we'd want two topology files, with HDMI being added in a second step when the kernel has it. I actually like this idea... Since HDMI is completely independent from the rest it'd be useful to add it conditionally.

[SQUASHME] ASoC: SOF : hda: better split between HDA and non-HDA support #257
runtime suspend/resume doesn't work when no hdmi pipelines defined in tplg file(with idisp BEs defined in machine driver). #234
