Merge tag 'renesas-soc-for-v3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/soc

Merge "Renesas ARM Based SoC Updates for v3.16" from Simon Horman:

SH Mobile shared SoC code
* Add shared shmobile_init_delay()

r8a7791 (R-Car M2) and r8a7790 (R-Car H2) SoCs (R-Car Gen2 shared code)
* Cache Mode Monitor Register Value

r8a7791 (R-Car M2) SoC
Check r8a7791 MD21 at SMP boot

r8a7790 (R-Car H2) SoC
* Make use of r8a7790_add_standard_devices()
* Update r8a7791 CPU freq to 1500MHz

r8a7778 (R-Car M1) SoC
* Move "select RENESAS_INTC_IRQPIN" under SoC

emev2 (Emma Mobale EV2) SoC
*  Remove legacy EMEV2 SoC support

* tag 'renesas-soc-for-v3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas:
  ARM: shmobile: r8a7778/bockw: Move "select RENESAS_INTC_IRQPIN" under SoC
