this is a rebased and updated version of the series I sent previously:

http://www.spinics.net/lists/arm-kernel/msg360709.html

Changes since v8:
 - Updated DT documentation example with IRQ_TYPE_... and
   IMX6QDL_CLK_... defines
 - Made PU regulator optional to support i.MX6SX, suggested by
   Robin Gong
 - Removed regulator_enable() call in the probe function, stopped
   disabling the regulator in imx6q_pm_pu_power_off() - the regulator
   framework will disable unused regulators.
 - Changed the GPC driver to enable pu power if CONFIG_PM is not
   enabled, as some bootloaders disable pu power on boot.

regards
Philipp
