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.
