Merge tag 'metag-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/jhogan/metag 

Pull Metag architecture changes from James Hogan:
 - Infrastructure and DT files for TZ1090 SoC (pin control drivers
   already merged via pinctrl tree).
 - Panic on boot instead of just warning if cache aliasing possible.
 - Various SMP/hotplug fixes.
 - Various other randconfig/sparse fixes.

* Meta Processor Binding



This binding specifies what properties must be available in the device tree

representation of a Meta Processor Core, which is the root node in the tree.



Required properties:



    - compatible: Specifies the compatibility list for the Meta processor.

      The type shall be <string> and the value shall include "img,meta".



Optional properties:



    - clocks: Clock consumer specifiers as described in

      Documentation/devicetree/bindings/clock/clock-bindings.txt



    - clock-names: Clock consumer names as described in

      Documentation/devicetree/bindings/clock/clock-bindings.txt.



Clocks are identified by name. Valid clocks are:



    - "core": The Meta core clock from which the Meta timers are derived.



* Examples



/ {

	compatible = "toumaz,tz1090", "img,meta";



	clocks = <&meta_core_clk>;

	clock-names = "core";

};
