Merge tag 'ux500-dt-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/fixes-non-critical
From Linus Walleij <linus.walleij@linaro.org>:
Ux500 Device Tree fixes
All are necessary to make a proper DT boot on the v3.9
series:
- IRQ edges.
- Register defines.
- FSMC clock.
- Ethernet clk fixup (one patch to drivers/net ACKed by
David Miller)
- Proper IOS and regulator voltages for MMCI.
- AB8500 GPIOs restored after they were fixed in the v3.9
merge window from the pinctrl tree.
- There is also a minor cleanup in the platform code, but it
is strongly connected to the other patches.
* tag 'ux500-dt-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
ARM: ux500: allow Snowball access to the AB8500 GPIO pins
