* Merge branch 'marco-timer-cleanup-rebase' of ↵Olof Johansson2013-01-28
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | git://gitorious.org/sirfprima2-kernel/sirfprima2-kernel into next/soc From Barry Song, this adds support for a new SoC from CSR; marco. It's SMP, uses GIC instead of VIC and in general needs a bit of rework of the platform code for setup, which this branch contains. * 'marco-timer-cleanup-rebase' of git://gitorious.org/sirfprima2-kernel/sirfprima2-kernel: ARM: PRIMA2: provide two DEBUG_LL ports for prima2 and marco ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructures ARM: PRIMA2: irq: make prima2 irq can work even we enable GIC for Marco ARM: PRIMA2: rtciobg: it is also compatible with marco ARM: PRIMA2: rstc: enable the support for Marco ARM: PRIMA2: mv timer to timer-prima2 as we will add timer-marco ARM: PRIMA2: initialize l2x0 according to mach from DT ARM: PRIMA2: enable AUTO_ZRELADDR for SIRF in Kconfig ARM: PRIMA2: add CSR SiRFmarco device tree .dts Signed-off-by: Olof Johansson <olof@lixom.net>

| | | | | | | | | | | | | | | | | | | | prima2 and marco has different memory base, the old code will fail if we enable DEBUG_LL in marco. this patch adds two debuf port, while debugging, we select one of PRIMA2 and MARCO debug ports, in the products, we disable DEBUG_LL.

| * ARM: PRIMA2: add new SiRFmarco SMP SoC infrastructuresBarry Song2013-01-22
| | | | | | | | | | | | | | | | | | | | | | | | this patch adds tick timer, smp entries and generic DT machine for SiRFmarco dual-core SMP chips. with the added marco, we change the defconfig, using the same defconfig, we get a zImage which can work on both prima2 and marco.

| * ARM: PRIMA2: irq: make prima2 irq can work even we enable GIC for MarcoBarry Song2013-01-22
| | | | | | | | | | | | | | | | in Marco, we will use GIC. this patch prepares the handle_irq for prima2 to avoid the compiling errors since we want only one defconfig and zImage for both prima2 and marco that means we will need handle_irq for both. Signed-off-by: Baohua Song <Baohua.Song@csr.com>

| * ARM: PRIMA2: mv timer to timer-prima2 as we will add timer-marcoBarry Song2013-01-22
| | | | | | | | | | | | | | | | | | | | Marco timer has different timer IP with prima2, so rename the current timer to timer-prima2 so that we can add timer-marco. at the same time, if we don't find prima2 timer node in dt, don't panic the system as we will make prima2 and marco use same kernel image.

At the moment, the only driver here is irq-bcm2835, the driver for the irq controller found in the ARM BCM2835 SoC, present in Rasberry Pi systems. This irq controller driver was exporting its initialization function and its irq handling function through a header file in <linux/irqchip/bcm2835.h>. When proposing to also move another irq controller driver in drivers/irqchip, Rob Herring raised the very valid point that moving things to drivers/irqchip was good in order to remove more stuff from arch/arm, but if it means adding gazillions of headers files in include/linux/irqchip/, it would not be very nice. So, upon the suggestion of Rob Herring and Arnd Bergmann, this commit introduces a small infrastructure that defines a central irqchip_init() function in drivers/irqchip/irqchip.c, which is meant to be called as the ->init_irq() callback of ARM platforms. This function calls of_irq_init() with an array of match strings and init functions generated from a special linker section. Note that the irq controller driver initialization function is responsible for setting the global handle_arch_irq() variable, so that ARM platforms no longer have to define the ->handle_irq field in their DT_MACHINE structure. A global header, <linux/irqchip.h> is also added to expose the single irqchip_init() function to the reset of the kernel. A further commit moves the BCM2835 irq controller driver to this new small infrastructure, therefore removing the include/linux/irqchip/ directory.

The main points are: 1) Convert arch_gettimeoffset to a pointer, so that architectures with multiple timer implementations can simply set this standard pointer rather than maintaining their own arch-specific pointers for the same purpose. Various architectures are converted to using this new feature. 2) Conversion of ARM timer implementations to use clock_event_devices's suspend/resume operations, rather than the ARM-specific sys_timer versions. Thus, the ARM code begins to use more common infra-structure rather than arch-specific code. 3) Removal of ARM's struct sys_timer completely, now that everything uses common code. 4) Introduction of drivers/clocksource/clksrc-of.c, which allows ARM clock source implementations to be moved into drivers/clocksource, with the need to add SoC-specific header files for each timer initialization function; instead, all enabled implementations are registered into a table which a single core function iterates over, and calls the relevant initialization functions based on device tree. At least the Tegra and BCM2835 clocksource implementations will use this feature in the 3.9 kernel cycle. * tag 'swarren-for-3.9-arm-timer-rework' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: clocksource: add common of_clksrc_init() function ARM: delete struct sys_timer ARM: remove struct sys_timer suspend and resume fields ARM: samsung: register syscore_ops for timer resume directly ARM: ux500: convert timer suspend/resume to clock_event_device ARM: sa1100: convert timer suspend/resume to clock_event_device ARM: pxa: convert timer suspend/resume to clock_event_device ARM: at91: convert timer suspend/resume to clock_event_device ARM: set arch_gettimeoffset directly m68k: set arch_gettimeoffset directly time: convert arch_gettimeoffset to a pointer cris: move usec/nsec conversion to do_slow_gettimeoffset Signed-off-by: Olof Johansson <olof@lixom.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is desirable to move all clocksource drivers to drivers/clocksource, yet each requires its own initialization function. We'd rather not pollute <linux/> with a header for each function. Instead, create a single of_clksrc_init() function which will determine which clocksource driver to initialize based on device tree.
