[PATCH 00/23] 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, 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, pipe_mask, has_vga and has_fuse to the power well struct and
perform the power well enable/disable sequence steps selectively based
on these.

The patchset here also includes a previous fixup series from me, it's
currently under review.
