[Intel-gfx] [PATCH v2 00/11] drm/i915: LPE audio runtime PM and multipipe (v2)

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Okay, here's the second attempt at getting multiple pipes playing back
audio on the VLV/CHV HDMI LPE audio device. The main change from v1 is
that now the PCM devices are associated with ports instead of pipes,
so the audio from one device always gets output on the same display.

I've also tacked on the alsa-lib conf update. No clue whether it's
really correct or not (the config language isn't a close friend
of mine).

BTW I did notice that with LPE audio all the controls say iface=PCM,
whereas on HDA a bunch of them say iface=MIXER. No idea if that's
OK or not, just something I spotted when I was comparing the results
with HDA.
