This device also requires a voltage regulator which

486095331a ARM: mach-shmobile: sh73a0: Minimal setup using DT
Allow a minimal setup of the sh73a0 SoC using a flattened device tree.
In particular, Configure the i2c controllers using a flattened device tree.

SCI serial controller and CMT clock source, whose drivers do not yet
support configuration using a flattened device tree, are still configured
using C code in order to allow booting of a board with this SoC.

*** Please note that the clock initialisation scheme used in
    this patch does not currently work with SMP as there
    is a yet to be resolved lock-up in workqueue initialisation.

    CONFIG_SMP must be disabled when using this code. ***

Includes update from Thierry Reding to no longer use gic_handle_irq()

0a4b04dc29 ARM: shmobile: use __iomem pointers for MMIO
ARM is moving to stricter checks on readl/write functions,
so we need to use the correct types everywhere.

This patch is a bit ugly for shmobile, which is the only platform
that just uses integer literals all over the place, but I can't
see a better way to do this.

33661c9e20 ARM: mach-shmobile: Kota2 TPU LED platform data
This patch updates the Kota2 board support code to
use the recently merged TPU LED driver whenever
possible.

The sh73a0 SoC has 5 TPU hardware blocks each with
4 timer channels which in theory allows a total of
20 LEDs to be controlled by "leds-renesas-tpu"
driver instances. The Kota2 board has 4 LEDs connected
to GPIO pins that also come with TPU pin functions, so
this patch ties up these 4 LEDS and leaves the remaining
3 LEDS for the GPIO based LED driver.

6d9598e24d ARM: mach-shmobile: Initial AG5 and AG5EVM support
This patch adds initial support for Renesas SH-Mobile AG5.

At this point the AG5 CPU support is limited to the ARM
core, SCIF serial and a CMT timer together with L2 cache
and the GIC. The AG5EVM board also supports Ethernet.

Future patches will add support for GPIO, INTCS, CPGA
and platform data / driver updates for devices such as
IIC, LCDC, FSI, KEYSC, CEU and SDHI among others.

The code in entry-macro.S will be cleaned up when the
ARM IRQ demux code improvements have been merged.

Depends on the AG5EVM mach-type recently registered but
not yet present in arch/arm/tools/mach-types.

As the AG5EVM board comes with 512MiB memory it is
recommended to turn on HIGHMEM.

Many thanks to Yoshii-san for initial bring up.
