Merge branch 'zynq/core-smp' of git://git.xilinx.com/linux-xlnx into next/soc2 

From Michal Simek <michal.simek@xilinx.com>:

This branch is based on zynq/clksrc/cleanup parts because
there are some dependencies on moving timer to generic location.

I could based it on standard Linux tagged version but you will get
several conflicts you will have to resolve.
If you are OK to resolving these problems, please let me know
I will create another branch with core-smp changes which are not based
on zynq/clksrc/cleanup branch.

* 'zynq/core-smp' of git://git.xilinx.com/linux-xlnx

:
  arm: zynq: Add hotplug support
  arm: zynq: Add smp support
  arm: zynq: Add smp_twd timer
  arm: zynq: Get rid of xilinx function prefix
  arm: zynq: Add support for system reset
  arm: zynq: Move slcr initialization to separate file
  arm: zynq: Load scu baseaddress at run time

Cadence TTC - Triple Timer Counter



Required properties:

- compatible : Should be "cdns,ttc".

- reg : Specifies base physical address and size of the registers.

- interrupts : A list of 3 interrupts; one per timer channel.

- clocks: phandle to the source clock



Example:



ttc0: ttc0@f8001000 {

	interrupt-parent = <&intc>;

	interrupts = < 0 10 4 0 11 4 0 12 4 >;

	compatible = "cdns,ttc";

	reg = <0xF8001000 0x1000>;

	clocks = <&cpu_clk 3>;

};
