[PATCH 0/5] sanitize hda/i915 interface using the component fw

The current hda/i915 interface to enable/disable power wells and query
the CD clock rate is based on looking up the relevant i915 module
symbols from the hda driver. By using the component framework we can get
rid of some global state tracking in the i915 driver and pave the way to
fully decouple the two drivers: once support is added to enable/disable
the HDMI functionality dynamically in the hda driver, it can bind/unbind
itself from the i915 component master, without the need to keep a
reference on the i915 module.

This also gets rid of the problem that currently the i915 driver exposes
the interface only on HSW and BDW, while it's also needed at least on
VLV/CHV.

Imre Deak (5):
drm/i915: add dev_to_i915_priv helper
drm/i915: add component support
ALSA: hda: pass chip to all i915 interface functions
ALSA: hda: add component support
drm/i915: remove unused power_well/get_cdclk_freq api
