Subject: [PATCH] drm/i915: Extend Fake HDMI live status to Valley View
On Atom E38xx based boards from two different manufacturers we have
encountered the HDMI display being disabled early during the boot process.
Extending the Fake HDMI live status to include Valley View chipsets
fixes this problem on both boards.
