ChangeLog v11->v12:
- Moved the pinctrl properties of the led1 and bp1 nodes to their respective parent nodes.
ChangeLog v10->v11:
- The other patches in this serie have already been applied in the for-next branch
in Shawn Guo's tree at git://git.linaro.org/people/shawnguo/linux-2.6.git :
4449d01 ARM i.MX35: build in pinctrl support.
cd01fd4 ARM: imx_v6_v7_defconfig: Enable some drivers used on the cpuimx35.
- Reordered the Cc list and dropped the Cc to the devicetree binding maintainers.
- Moved the pins of the hoggrp inside their respective node, the bp1 and led1 nodes
were updated accordingly.
- The esdhc1's gpio was fixed: the card detect code will never uses the gpio "active"
high/low setting, instead it uses that GPIO as an IRQ.
- Cosmetic fixes in the uart pinctrl nodes.
ChangeLog v9->v10:
- Added Fabio Estevam To the Cc list
ChangeLog v8->v9:
- Added the dtb target into arch/arm/boot/dts/Makefile.
- Added a blank line before the pcf8563 node in the i2c1 node.
- Whitespace cleanups as requested by Shawn Guo.
- _' was used in label, it's now fixed (it has been replaced with '-').
- The recently introduced defines for input and gpios are now used.
- The uarts had the fsl,uart-has-rtscts property set, but they didn't use
any rts and cts pins in the uart pinctrl nodes.
ChangeLog v7->v8:
- The commit message was improved.
- The board specific iomuxc pins group configuration that were in imx35.dtsi were moved here.
- The rest of the patch was updated accordingly.
ChangeLog v6->v7:
- Added Grant Likely in the Cc list.
- Shortened the license.
- The tsc2007 pads were moved in another patch.
ChangeLog v5->v6:
- Shawn Guo was added in the Cc.
