Haswell Display audio depends on power well in graphic side, it should
request power well before use it and release power well after use.
I915 will not shutdown power well if it detects audio is using.
This patch protects display audio crash for Intel Haswell C3 stepping board.

For Intel Haswell chip, HDA controller and codec have
power well dependency from GPU side. This patch added support
to request/release power well in audio driver. Power save
feature should be enabled to get runtime power saving.
There's deadlock when request_module(i915) in azx_probe.
It looks lik

This is a preliminary work for the upcoming Haswell HDMI audio fixes.
azx_first_init() function can be safely called after the f/w loader,
since the f/w loader doesn't require the sound hardware initialization
beforehand. Moving it into azx_probe_continue() cleans up the code
The device can support runtime PM no matter whether it support
signal wakeup or not. For some chips like Haswell which doesnot
support PME by default, this patch let haswell Display HD-A controller
enter runtime suspend, and bring more power saving whith power-well
feature enabled.

Hi all,
This is V7 and here're some changes notes:
change from V6-->V7:
- rename variable
- use HAS_POWER_WELL instead of IS_HASWELL
- put structure inside drm_i915_private
- use WARN_ON for global pointer check
change from V5-->V6:
- Remove duplication code in new introdu
Only lvds/tv did actually check for cloning or not, but many more
places should.
Notices because my ivb tried to enable both cpu edp and vga on the
first crtc - the resulting confusion between has_pch_encoder,
has_dp_encoder but not actually being a pch dp encoder resulting in

Hi Damien,
Thanks your review, comments inline. :)
