[PATCH 01/10] ARM: ux500: move AB8500 GPIOs to device tree
Linus Walleij
linus.walleij at linaro.org
Tue Feb 4 14:52:17 EST 2014
Move the AB8500 muxing and biasing settings over from the board
file to the device tree, include it in the reference designs using
the AB8500: HREF prior to v60, v60plus and Snowball. Set up these
GPIO lines using hogs, just like in the board file.
