From Simon Horman:

Second Round of Renesas ARM-based SoC DT updates for v3.11

* Increased DT coverage for renesas-intc-irqpin
  by Guennadi Liakhovetski
* Clean up of address format used in sh73a0 dtsi file
  by Guennadi Liakhovetski

* tag 'renesas-dt2-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: shmobile: irqpin: add a DT property to enable masking on parent
  ARM: shmobile: sh73a0: remove "0x" prefix from DT node names
  irqchip: renesas-intc-irqpin: DT binding for sense bitfield width

+DT bindings for the R-/SH-Mobile irqpin controller
+
+Required properties:
+
+- compatible: has to be "renesas,intc-irqpin"
+- #interrupt-cells: has to be <2>: an interrupt index and flags, as defined in
+  interrupts.txt in this directory
+
+Optional properties:
+
+- any properties, listed in interrupts.txt, and any standard resource allocation
+  properties
+- sense-bitfield-width: width of a single sense bitfield in the SENSE register,
+  if different from the default 4 bits
+- control-parent: disable and enable interrupts on the parent interrupt
+  controller, needed for some broken implementations
