From: Linus Walleij Date: Wed, 13 Nov 2013 13:45:06 +0000 (+0100) Subject: ARM: ux500: move MSP pin control to the device tree X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=70b41abc151f9;p=linux-beck.git ARM: ux500: move MSP pin control to the device tree This moves the static, device-tied pin control configuration out of the board file board-mop500-pins.c and into the device tree. Add nodes for MSP0 and MSP2 on the HREF and Snowball so we can reference the pins properly.
