Subject: [PATCH 04/21] ARM: ux500: move MSP pin control to the device tree
Date: Sun, 17 Nov 2013 12:03:53 +0100 [thread overview]
Message-ID: <1384686250-10542-5-git-send-email-linus.walleij@linaro.org> (raw)
In-Reply-To: <1384686250-10542-1-git-send-email-linus.walleij@linaro.org>
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.
