7d6b888354 ARM: shmobile: sh73a0: Remove init_irq declaration in machine description
Commit ebafed7a ("ARM: irq: Call irqchip_init if no init_irq function is
specified") removed the need to explictly setup the init_irq field in
the machine description when using only irqchip_init. Remove that
declaration for shmobile as well.

43cb8cb739 ARM: shmobile: sh73a0: Always use shmobile_setup_delay()
Break out the function sh73a0_init_delay() that now
gets called both for the C version of the code and
the DT -reference boards. This way we handle both
cases in the same way.

Allows us to boot with TWD only in the kernel configuration
for C board code. TWD is not yet enabled in the case of
DT -reference - this due to a dependency on CCF.

Update the CMT clockevent rating from 125 to 80.

This resolves a boot-failure regression for kzm9g-reference in v3.10-rc1

Avoid dummy clockevent being preferred over real").

The patch noted above reduces the rating of dummy clockevent from 400 to 100.
This patch reduces the rating of CMT so that it is once again less than that

This has a nasty set of conflicts with the exynos MCT code, which was
moved in a separate branch, and then fixed up when merged in, but still
conflicts a bit here. It should have been sorted out by this merge though.

0583fe478a ARM: convert arm/arm64 arch timer to use CLKSRC_OF init
This converts arm and arm64 to use CLKSRC_OF DT based initialization for
the arch timer. A new function arch_timer_arch_init is added to allow for
arch specific setup.

This has a side effect of enabling sched_clock on omap5 and exynos5. There
should not be any reason not to use the arch timers for sched_clock.

Adjust the sh73a0 IRQ code to make use of the
INTC External IRQ pin driver for external
interrupt pins IRQ0 -> IRQ31.

This removes quite a bit of special-case code
in intc-sh73a0.c but the number of lines get
replaced with platform device information in
setup-sh73a0.c. The PFC code is also adjusted
to make gpio_to_irq() return the correct
interrupt number.

At this point the DT reference implementations
are not covered. In the future such code shall
tie in the INTC External IRQ pin driver via
DT, so this kind of verbose code is not needed
for the long term DT case.

 	* Rework of the way the Tegra IOMMU driver accesses its

7ae1c76ee5 arm-soc: pin muxing for sh-mobile
This is another cleanup series, containing the move of the Renesas
 SH-Mobile pin controller code from arch/arm/mach-shmobile over to the
 generic pinctrl subsystem, changing it over to the common interfaces in
 the process.
 
 Based on agreement between Olof, Paul Mundt, Linus Walleij and Simon,
 we're merging this large branch of pinctrl conversion through arm-soc,
 even though it contains the corresponding conversions for arch/sh. Main
 reason for this is tight dependencies (that will now mostly be broken)
 between the arch/sh and mach-shmobile implementations.
 
 There will be more of this in 3.10 to do device-tree bindings, but this
 is the initial conversion.

This patch adds an IPMMU device and notifies the IPMMU driver which
devices are connected via the IPMMU module.  All devices connected to the main
memory bus via the IPMMU module MUST be registered when SHMOBILE_IPMMU and
SHMOBILE_IOMMU are enabled because physical address cannot be used
while the IPMMU module's MMU function is enabled.

6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

 Beyond that there's some conversions of clock infrastructure on tegra

 This branch adds two new directories outside of arch/arm:
 drivers/irqchip for new irq controllers, and drivers/bus for the above
 OMAP bus. It's expected that some of the other platforms will migrate
 parts of their platforms to those directories over time as well.

Fix SMP TWD boot regression on sh73a0 based platforms caused by:

4200b16 ARM: shmobile: convert to twd_local_timer_register() interface

After the merge of the above commit it has been impossible to boot
sh73a0 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The
kernel crashes at smp_init_cpus() timing which is before the console
has been initialized, so to the user this looks like a kernel lock up
without any particular error message.

This patch fixes the regression on sh73a0 by moving the TWD
registration code from smp_init_cpus() to sys_timer->init() time.

This patch removed shmobile_twd_init() which is no longer needed

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.
