Subject: [PATCH] ARM: dts: omap3-beagle-xm: enable pullup for dvi on twl_gpio
Date: Fri, 20 Sep 2013 14:52:16 -0500 [thread overview]
Message-ID: <1379706736-4041-1-git-send-email-robertcnelson@gmail.com> (raw)
From: Robert Nelson <robertcnelson-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
This fixes some video sync issues seen with KVM equipment on bootup, with
omapdrm/kms by making sure the TFP410 is powered up, via pulling up GPIO2 on
the twl4030.
