Subject: [PATCH 12/16] drm/i915: Fix CHV DSI PLL refclk during state readout
Date: Tue, 15 Mar 2016 16:40:05 +0200	[thread overview]
Message-ID: <1458052809-23426-13-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1458052809-23426-1-git-send-email-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Use the proper refclock frequency (100MHz) when reading out the
current DSI clock on CHV.
