Merge tag 'imx-soc-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/soc
Merge "i.MX SoC update for 4.6" from Shawn Guo:
- Enable big endian mode support for i.MX platform
- Add support for i.MX6QP SoC which is the latest i.MX6 family addition
- Add basic suspend/resume support for i.MX25
- A couple of i.MX7D support updates
- A few random code cleanups
* tag 'imx-soc-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux:
ARM: imx: Make reset_control_ops const
ARM: imx: Do L2 errata only if the L2 cache isn't enabled
ARM: imx: select ARM_CPU_SUSPEND only for imx6
ARM: mx25: Add basic suspend/resume support
ARM: imx: Add msl code support for imx6qp
ARM: imx: enable big endian mode
ARM: imx: use endian-safe readl/readw/writel/writew
ARM: imx7d: correct chip version information
ARM: imx: select HAVE_ARM_ARCH_TIMER if selected i.MX7D
ARM: imx6: fix cleanup path in imx6q_suspend_init()
