| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

| * ARM: convert arm/arm64 arch timer to use CLKSRC_OF initRob Herring2013-04-111-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Beyond that there's some conversions of clock infrastructure on tegra to common clock, misc updates for several other platforms, and OMAP now has its own bus (under drivers/bus) to manage its devices through. This branch adds two new directories outside of arch/arm: drivers/irqchip for new irq controllers, and drivers/bus for the above OMAP bus.

| | | | | | | | | | | | Current shdmac can support MPDMAC (= sound DMA) on sh73a0. This support reduce CPU load when sound was playback. On v2.0 manual, MPDMAC MID/RID number were wrong. This patch is using the number which seems correct. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J.

* ARM / mach-shmobile: sh73a0 SMP TWD boot regression fixKuninori Morimoto2012-05-121-0/+4
| | | | | | | | | | | | | | | | | | | | | 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 Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J.

* ARM: mach-shmobile: Initial AG5 and AG5EVM supportMagnus Damm2010-11-181-0/+234
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.
