This patch certainly doesn't cause any additional issues for me, so:
Tested-by: Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
Howwever, it still doesn't allow both Cardhu's LCD panel and external
HDMI port (1080p) to be active at once. If I boot with both enabled, or
boot with just the LCD enabled and hot-plug HDMI, as soon as both heads
are active, then some kind of display corruption starts; it looks like a
clocking issue or perhaps memory underflow.
Mark, can you please investigate this. I haven't tested to see if the
issue is Tegra30-specific, or also happens on Tegra20.
