Merge tag 'imx-fixes-4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes

Merge "ARM: imx: fixes for 4.2" from Shawn Guo:

The i.MX fixes for 4.2:
 - Correct compatible string for i.MX27 GPT which actually shares the
   same programming model as i.MX21 GPT rather than i.MX1 one.
 - Add missing #io-channel-cells property for i.MX23 LRADC device, which
   is required for the device to be an IIO provider.
 - Correct HSYNC/VSYNC pins and add ddc-i2c-bus property for TVE device
   on imx53-qsb to work properly.
 - Always enable PU domain if CONFIG_PM is not set.  This fixes a couple
   of failure scenarios which will hang the system if one of the devices
   in the PU domain is accessed.
