Merge tag 'imx-soc-4.3' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/soc

The i.MX SoC changes for 4.3:
 - Add i.MX6 Ultralite SoC support, which is the newest addition to
   i.MX6 family.  It integrates a single Cortex-A7 core and a power
   management module that reduces the complexity of external power
   supply and simplifies power sequencing.
 - Change SNVS RTC driver to use syscon interface for register access,
   and add SNVS power key driver support.
 - Add a second clock for mxc rtc driver, and support device tree probe
   for the driver.
 - Add FEC MAC reference clock and phy fixup initialization for i.MX6UL
   platform.
