Subject: [PATCH 09/14] drm/i915: Fix CHV DSI PLL refclk during state readout
Date: Thu, 3 Sep 2015 21:50:11 +0300 [thread overview]
Message-ID: <1441306216-6581-10-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1441306216-6581-1-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.
