Merge tag 'imx-cleanup-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/cleanup
Pull "The i.MX cleanup for 3.19" from Shawn Guo:
- Clean up reset handler for DT machines, since reset has been handled
in watchdog driver
- Remove unneeded .map_io hook for a couple of i.MX6 machines
- A few small i.MX6 device tree source cleanups
- Some random iomuxc and pllv3 code cleanup
