Merge tag 'renesas-cleanup2-for-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/renesas
From Simon Horman:
Second round of Renesas ARM based SoC cleanups for v3.12
* Remove mach/hardware.h which has no useful contents
* Remove ag5evm board support
* Remove kota2 board support
* Use pm-rmobile on sh7372 and r8a7740 SoCs only, it is otherwise unneeded
* Remove use of INTC header on r8a7779 and r8a7740 SoCs
* Cleanup registration of usb phy in r8a7779 SoC
* Remove '0x's from R8A7779 DTS file for r8a7779 SoC
* tag 'renesas-cleanup2-for-v3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas: (74 commits)
