Merge tag 'renesas-soc2-for-v3.13' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/soc

From Simon Horman:
Second Round of Renesas ARM based SoC updates for v3.13

* SMP support for r8a7791 SoC
* r8a7779_init_irq_extpin() for DT for r8a7779 and r8a7778 SoCs
* Add HPB-DMAC to r8a7779 and r8a7778 SoCs
* Add r7s72100 SoC
* Make use of ARCH timer workaround on r8a7791 SoC
* Add IRQC platform device support to r8a7791 SoC
* Add I2C clocks and aliases for the DT mode for r8a7790 SoC
* Add MAC platform device to r8a73a4 SoC
