Merge tag 'renesas-dt2-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/dt
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 Signed-off-by: Arnd Bergmann <arnd@arndb.de>
