Subject: [Intel-gfx] [PATCH v2 3/3] drm/i915/icl: Cleanup combo PHY aux power well handlers
Date: Thu, 12 Dec 2019 15:51:21 -0800	[thread overview]
Message-ID: <20191212235121.668922-1-matthew.d.roper@intel.com> (raw)
In-Reply-To: <20191212230411.bx6xb6ixhullrki7@ldmartin-desk1>

Now that the combo PHY aux power well handlers are used exclusively on
Icelake, we can drop a bunch of the extra tests.

v2: Don't try to use intel_uncore_rmw for register updates yet; there's
    pending display uncore patches that need to land first.  (Lucas)
