[Intel-gfx] [PATCH 0/3] AUX power well fixes

[Matt Roper]

A few fixes related to AUX power wells for various platforms:
 * EHL shouldn't use TC power well handling on C/D since all of its
   outputs are combo.
 * TGL shouldn't be applying Display WA #1178; doing so causes failures
   to enable power wells in some cases.

There's some ambiguity as to whether WA#1178 is even still relevant to
ICL or not; we're checking with the hardware architects on that, but
this series leaves it in place for ICL for now.

Matt Roper (3):
  drm/i915/ehl: Define EHL powerwells independently of ICL
  drm/i915/tgl: Drop Wa#1178
  drm/i915/icl: Cleanup combo PHY aux power well handlers
