[PATCH 00/18] drm/i915: Unify the HSW/BDW and GEN9+ power well code

[Imre Deak]

The programming of display power wells starting from HSW is pretty
similar on all platforms, but we have separate code for HSW/BDW and
GEN9+ platforms. This patchset unifies the two for clarity and to make
it easier to add power well support for future platforms. In essence
this means adding 3 attributes, irq_pipe_mask, has_vga and has_fuses
to the power well struct and perform the power well enable/disable
sequence steps selectively depending on these.

Imre Deak (18):
  drm/i915/chv: Add unique power well ID for the pipe A power well
  drm/i915: Unify power well ID enums
  drm/i915: Assign everywhere the always-on power well ID
  drm/i915/gen2: Add an ID for the display pipes power well
  drm/i915/hsw,bdw: Add an ID for the global display power well
  drm/i915: Check for duplicated power well IDs
  drm/i915/bxt,glk: Give a proper name to the power well struct phy
    field
  drm/i915/gen9+: Remove redundant power well state assert during
    enabling
  drm/i915/gen9+: Remove redundant state check during power well
    toggling
  drm/i915/hsw,bdw: Remove redundant state check during power well
    toggling
  drm/i915/hsw,bdw: Split power well set to enable/disable helpers
  drm/i915/hsw+: Unify the hsw/bdw and gen9+ power well req/state macros
  drm/i915/hsw,bdw: Add irq_pipe_mask, has_vga power well attributes
  drm/i915/hsw,bdw: Wait for the power well disabled state
  drm/i915/hsw+: Add has_fuses power well attribute
  drm/i915/gen9+: Unify the HSW/BDW and GEN9+ power well helpers
  drm/i915: Move hsw_power_well_enable() next to the rest of HSW helpers
  drm/i915: Gather all the power well->domain mappings to one place
