Merge tag 'renesas-dt-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/dt

From Simon Horman:
Renesas ARM-based SoC DT updates for v3.11

* Armadillo800eva reference DT - bring up armadillo800eva baord
  using DT as much as possible
* Remove unused GIC dtsi entries for r8a7790 and r8a73a4
* Add AS3711 and CPUFreq DT bindings for kzm9g-reference
* Add irqpin DT support for marzen-reference

* tag 'renesas-dt-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: shmobile: marzen-reference: add irqpin support in DT
  ARM: shmobile: kzm9g-reference: add AS3711 and CPUFreq DT bindings
  ARM: shmobile: armadillo800eva: Reference DT implementation
  ARM: shmobile: Remove unused r8a7790 GIC CPU interface DT bits
  ARM: shmobile: Remove unused r8a73a4 GIC CPU interface DT bits
  ARM: shmobile: r8a7740: Prepare for reference DT setup
  ARM: shmobile: r8a7740: Add OF support to initialze the GIC
