From Shawn Guo:
mxs device tree changes for 3.9

 - Mostly cfa100xx related device tree source updates

* tag 'mxs-dt-3.9' of git://git.linaro.org/people/shawnguo/linux-2.6:
  ARM: mxs: dts: Add rotary encoder to the CFA-10049
  ARM: mxs: dts: Add gpio-keys for the rotary to the CFA-10049
  ARM: dts: mxs: Add the LCD to the 10049 board
  ARM: dts: mxs: Add muxing options for the third PWM
  ARM: dts: cfa10049: Change the SPI3 bus to spi-gpio
  ARM: mxs: dt: Add Crystalfontz CFA-10037 device tree support
  ARM: mxs: Enable touchscreen on m28evk
  ARM: dts: cfa10049: Add PCA9555 GPIO expander to the device tree
