Subject: [PATCH 06/15] gma500: Make crtc count a property of the device
From: Alan Cox <alan@...ux.intel.com>
Octavian Purdila posted a patch that sets num_crtc to 1 for Moorestown, but
Oaktrail has 2 so we need to split Oaktrail/Moorestown more sensibly, and
also cope with some other differences later on.
