From: Igor Grinberg Date: Tue, 5 Jul 2011 10:38:23 +0000 (-0700) Subject: arm: omap3: cm-t35: add support for cm-t3730 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c31469747854a1f1dcfd81a8fb1d9865c3ee58b9;p=linux-beck.git arm: omap3: cm-t35: add support for cm-t3730 cm-t3730 is basically the same board as cm-t35, but has AM/DM3730 SoC assembled and therefore some changes are required.
