[PATCH 0/6] drm/i915: refactor VLV IOSF SB for display usage

[Jani Nikula <jani.nikula@intel.com>]

In short, add and use generic (not unit specific) read/write/get/put for
i915 core, move the unit specific helpers to display, and convert all of
them to use drm_display instead of drm_i915_private. This reduces the
display<->i915 interface to just a handful of functions, while keeping
the simple helpers in display where they are most commonly used.


Jani Nikula (6):
  drm/i915: rename vlv_sideband*.[ch] to vlv_iosf_sb*.[ch]
  drm/i915: add generic read/write functions for VLV IOSF SB
  drm/i915: rewrite VLV IOSF SB unit specific read/write functions
  drm/i915: switch i915 core to generic VLV IOSF SB functions
  drm/i915: move VLV IOSF SB unit specific helpers under display
  drm/i915: convert VLV IOSF SB interface to struct drm_device
