Merge tag 'integrator-for-v3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator into next/drivers

From Linus Walleij:
Some Integrator patches that matured for v3.14:

- Use PATCH_PHYS_TO_VIRT and AUTO_ZRELADDR.
- Support cascaded interrupts on the SIC.
- Complete clock implementation for the IM-PD1.

* tag 'integrator-for-v3.14' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-integrator

:
  clk: versatile: fixup IM-PD1 clock implementation
  clk: versatile: pass a name to ICST clock provider
  ARM: integrator: pass parent IRQ to the SIC
  irqchip: versatile FPGA: support cascaded interrupts from DT
  ARM: integrator: Default enable ARM_PATCH_PHYS_VIRT, AUTO_ZRELADDR

Optional properties:

- interrupts: if the FPGA IRQ controller is cascaded, i.e. if its IRQ

  output is simply connected to the input of another IRQ controller,

  then the parent IRQ shall be specified in this property.
