Merge tag 'keystone-soc-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone into next/soc

From Santosh Shilimkar:
SOC support for Keystone II devices:
- Minimal machine and device-tree support with arch_timers and console UART
- Reboot hook using PLL reset
- Low level debug support using UART
- SMP boot support

* tag 'keystone-soc-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/ssantosh/linux-keystone:
  ARM: keystone: Enable SMP support on Keystone machines
  ARM: keystone: Add minimal TI Keystone platform support
  ARM: dts: keystone: Add minimal Keystone SOC device tree data
