2013-03-18ARM: shmobile: Make sh73a0 INTC irqpin platform data staticMagnus Damm
The platform data for the INTC irq pin driver seems to be global symbols, make it static to allow multi-soc build. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-03-18ARM: shmobile: INTC External IRQ pin driver on sh73a0Magnus Damm
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.

2013-03-13ARM: shmobile: sh73a0: Do not use early devices with DT referenceSimon Horman
Do not initialise any early devices when using the minimal DT reference code. Only the delay needs to be initialised. Cc: Magnus Damm <magnus.damm@gmail.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>
2013-03-13ARM: shmobile: sh73a0: Remove warning about SMPSimon Horman
Remove warning about SMP not working with the clock initialisation sheme used for reference DT. This is resolved by not selecting CONFIG_PREEMPT. Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

2013-03-13ARM: shmobile: sh73a0: Remove sh73a0_init_irq_dt()Simon Horman
This is not needed as irq_set_wake is only used for suspend to ram which is not a requirement for bringing up boards using DT. Reported-by: Magnus Damm <magnus.damm@gmail.com> Signed-off-by: Simon Horman <horms+renesas@verge.net.au>

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.

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.

2012-12-24ARM: delete struct sys_timerStephen Warren
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.

Pull ARM soc-specific updates from Olof Johansson: "Most notable here is probably the addition of basic support for the BCM2835, an SoC used in some of the Roku 2 players as well as the much-hyped Raspberry Pi, cleaned up and contributed by Stephen Warren. It's still early days on mainline support, with just the basics working. But it has to start somewhere! 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. It's expected that some of the other platforms will migrate parts of their platforms to those directories over time as well."

2012-09-18ARM: shmobile: use __iomem pointers for MMIOArnd Bergmann
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.

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 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.
