687c27b070 ARM: shmobile: r8a7791 SMP support
Tie in the APMU SMP code on r8a7791. When used together
with the secondary CPU device node and smp_ops in the
board specific code then this will allow use of the
two Cortex-A15 cores in the r8a7791 SoC.

454d320c80 ARM: shmobile: r8a7791 IRQC platform device support
Add a platform device for the r8a7791 IRQC hardware
driving IRQ pins IRQ0 to IRQ9. The Linux interrupt
number is statically assigned to allow board code
written in C to make use of static interrupt numbers.

4275881fca ARM: shmobile: Introduce r8a7791_add_standard_devices()
Introduce the function r8a7791_add_standard_devices() that
follows the same style as other mach-shmobile SoC code and
allows C version of board code to add on-chip devices.

1bebd72a71 ARM: shmobile: r8a7791 CMT support
Add r8a7791 CMT support via channel 0 of CMT0. At this
point the CMT is used for clock event operation, but in
the future the arch timer will be the main timer and the
CMT will be used for deep sleep wake up only.

e6491d08ed ARM: shmobile: r8a7791 SCIF support
Add SCIF serial port support to the r8a7791 SoC by
adding platform devices for SCIFA0 -> SCIFA5 as well
as SCIFB0 -> SCIFB2 and SCIF0 -> SCIF5 together with
clock bindings. DT device description is excluded at
this point since such bindings are still under
development.

0d0771ab2b ARM: shmobile: Initial r8a7791 SoC support
Add initial support for the r8a7791 SoC including:
 - Single Cortex-A15 CPU Core
 - GIC

No static virtual mappings are used, all the components
make use of ioremap(). DT_MACHINE_START is still wrapped
in CONFIG_USE_OF to match other mach-shmobile code.
