Subject: [PATCH 1/3] drm/i915: Clear shared dpll based on old state.
Date: Tue,  9 Feb 2016 13:52:21 +0100	[thread overview]
Message-ID: <1455022343-15222-1-git-send-email-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20160203163408.GF23290@intel.com>

Atomic resume was preserving the dpll state because it was required
for clearing pll state correctly. If we look at the old_crtc_state
for pll to clear this is not needed and the hack can be removed.
