Geert Uytterhoeven d9e1a0ef45 ARM: shmobile: r7s72100 dtsi: Use "arm,pl390" for GIC
Replace the "arm,cortex-a9-gic" compatible value for the GIC by
"arm,pl390", as the documentation states it is a PL390.
This has been confirmed (thanks Chris, Wolfram!) by reading the
GICD_IIDR register, which reports 0x0000043b (PL390 = 0x00, ARM =
0x43b).

This has no effect on runtime behavior, as currently the GIC driver
treats both compatible values the same.

Geert Uytterhoeven cbe1f83818 ARM: shmobile: r7s72100 dtsi: Add CPG/MSTP Clock Domain
Add an appropriate "#power-domain-cells" property to the cpg_clocks
device node, to create the CPG/MSTP Clock Domain.

Add "power-domains" properties to all device nodes for devices that are
part of the CPG/MSTP Clock Domain and can be power-managed through an
MSTP clock.  This applies to most on-SoC devices, which have a
one-to-one mapping from SoC device to DT device node.

Simon Horman f401ce4810 ARM: shmobile: r7s72100: Use SoC-specific MTU2 compat string
In general Renesas hardware is not documented to the extent
where the relationship between IP blocks on different SoCs can be assumed
although they may appear to operate the same way. Furthermore the
documentation typically does not specify a version for individual
IP blocks. For these reasons a convention of using the SoC name in place
of a version and providing SoC-specific compat strings has been adopted.

Although not universally liked this convention is used in the bindings for
a number of drivers for Renesas hardware. The purpose of this patch is to
make use of the SoC-specific CMT compat string for the r7s72100 MTU2
clock source.

Magnus Damm 005407fdf1 ARM: shmobile: Update r7s72100 DTS to include CPU frequency
Add CPU Frequency information to the r7s72100 DTS file. This
will allow us to use the shared C code on r7s72100 and Genmai
which reads out the clock frequency from DT and calculates the
delay settings from there.

Add initial support for the r7272100 SoC including:
 - Single Cortex-A9 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.
