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) ARM: shmobile: r8a7779: Remove '0x's from R8A7779 DTS file ARM: shmobile: r8a7779: cleanup registration of usb phy ARM: shmobile: No need to use INTC header on r8a7779 ARM: shmobile: No need to use INTC demux on r8a7740 ARM: shmobile: Use pm-rmobile on sh7372 and r8a7740 only ARM: shmobile: r8a73a4: Remove ->init_machine() special case ARM: shmobile: Remove include <mach/hardware.h> ARM: shmobile: Remove Marzen use of <mach/hardware.h> ARM: shmobile: Remove r8a7779 use of <mach/hardware.h> ARM: shmobile: Remove EMEV2 use of <mach/hardware.h> ARM: shmobile: Remove sh7372 use of <mach/hardware.h> ARM: shmobile: Remove sh73a0 use of <mach/hardware.h> ARCH: ARM: shmobile: Remove ag5evm board support ARCH: ARM: shmobile: Remove kota2 board support leds: Remove leds-renesas-tpu driver ARM: shmobile: sh73a0: Remove all GPIOs ARM: shmobile: kota2: Use leds-pwm + pwm-rmob ARM: shmobile: armadillo800eva: Add backlight support ARM: shmobile: Setup r8a7790 arch timer based on MD pins ARM: shmobile: Introduce r8a7790_read_mode_pins() ...
