X-Git-Tag: v2015.01-rc2~4^2~29
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=12fe7f7c2a0aaa4902e920ca8cc8608ebc30effe;p=oweals%2Fu-boot.git

dm: at91: Add platform data for GPIO on at91sam9260-based boards

These boards all have the same GPIO arrangement, so add some common platform
data that can be used by all boards. Remove the configs which are no longer
required.
