[PATCH 17/21] ARM: ux500: move HREFv60plus pin configs to device tree
Linus Walleij
linus.walleij at linaro.org
Sun Nov 17 06:04:06 EST 2013
Move the few remaining HREFv60 pin configurations to the device
tree, reference these as hogs to the pin controller until there
are real devices that can make use of them.
