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.

This patch enables the use of the generic cpufreq-cpu0 driver on sh73a0. Providing a regulator, a list of OPPs in DT, combined with a virtual cpufreq-cpu0 platform device and a clock, attached to it is everything, the cpufreq-cpu0 driver needs. The first sh73a0 platform, implementing such CPUFreq support is kzm9g-reference.

Update the CMT clockevent rating from 125 to 80. This resolves a boot-failure regression for kzm9g-reference in v3.10-rc1 introduced by f7db706b ("ARM: 7674/1: smp: 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 of the dummy clockevent.

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.

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.

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: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

Fix SMP TWD boot regression on sh73a0 based platforms caused by: 4200b16d 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 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.
