clocksource: add common of_clksrc_init() function 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. Based on a similar patch for drivers/irqchip by Thomas Petazzoni. Signed-off-by: Stephen Warren <swarren@nvidia.com>

atmel_tc clocksource/clockevent code Clocksource and clockevent device based on the Atmel TC blocks. The clockevent device handles both periodic and oneshot modes, so this enables NO_HZ and high res timers on some platforms that previously couldn't use those mechanisms. This works on both AVR32 and AT91 chips, given relevant patches for tclib support (always) and clockevents (or else this will only look like a higher precision clocksource). It's an updated and modularized version of an AT91-only patch that has circulated for some time now. Changes relative to the original patch: * Update to use new tclib API * Replace open-coded do-while loop using goto with a real do-while loop * Minor irq handler optimization: Load register base address from dev_id instead of a global variable. * Aggressively turn off clocks when the clockevent isn't being used * Include the clockevent code on AT91RM9200 as well. The rating is lower than the System Timer, so the clock will usually stay off. * Don't assume that the number of clocks is always equal to the number of irqs.

cs5535: add a generic clock event MFGPT driver This is based on the old code in arch/x86/kernel/mfgpt_32.c, but is modular and not Geode-specific. There's no reason why the clock event device needs to be registered so early at boot; the clockevent code is perfectly capable of dynamic switching.

sh: CMT clockevent platform driver SuperH CMT clockevent driver. Both 16-bit and 32-bit CMT versions are supported, but only 32-bit is tested. This driver contains support for both clockevents and clocksources, but no unregistration is supported at this point. Works fine as clock source and/or event in periodic or oneshot mode. Tested on sh7722 and sh7723, but should work with any cpu/architecture. This version is lacking clocksource and early platform driver support for now - this to minimize the amount of dependencies.

The MTU2 driver is a platform driver with early platform support to allow using a MTU2 channel as only clockevent during system bootup. Clocksource on sh2a is currently unsupported due to code generation issues with 64-bit math, so at this point only periodic clockevent support is in place.

clocksource: em_sti: Emma Mobile STI driver The STI hardware is based on a single 48-bit 32kHz counter that together with two individual compare registers can generate interrupts. There are no timer operating modes selectable which means that the timer can not clear on match. This driver is providing clocksource support for the 48-bit counter. Clockevents are also supported using the same timer in oneshot mode.

ARM: plat-nomadik: move MTU, kill plat-nomadik This moves the MTU timer driver from arch/arm/plat-nomadik to drivers/clocksource and moves the header file to the platform_data directory. As this moves the last file being compiled to an object out of arch/arm/plat-nomadik, we have to "turn off the light" and delete the plat-nomadik directory, because it is not allowed to have an empty Makefile in a plat-* directory. This is probably also a desired side effect of depopulating the arch/arm directory of drivers. Luckily we have just deleted all the <plat/*> include files prior to this so by moving the last one we may delete the directory. After this all the Ux500 and Nomadik device drivers live outside of the arch/arm hierarchy.

ARM: bcm2835: add system timer The System Timer peripheral provides four 32-bit timer channels and a single 64-bit free running counter. Each channel has an output compare register, which is compared against the 32 least significant bits of the free running counter values, and generates an interrupt. Timer 3 is used as the Linux timer. The BCM2835 also contains an SP804-based timer module. However, it apparently has significant differences from the standard SP804 IP block, and Broadcom's documentation recommends using the system timer instead. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split as of 2012/09/08, and modified as follows: * s/bcm2708/bcm2835/. * Modified device tree vendor prefix. * Moved to drivers/clocksource/. This looks like the desired location for such code now. * Added DT binding docs. * Moved struct sys_timer bcm2835_timer into time.c to encapsulate it more. * Simplified bcm2835_time_init() to find one matching node and operate on it, rather than looping over all matching nodes. This seems more consistent with other clocksource code. * Simplified bcm2835_time_init() using of_iomap(). * Renamed struct bcm2835_timer.index to match_mask to better represent its purpose. * s/printk(PR_INFO/pr_info(/ Signed-off-by: Chris Boot <bootc@bootc.net> Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Signed-off-by: Dom Cobley <popcornmix@gmail.com> Signed-off-by: Dom Cobley <dc4@broadcom.com> Signed-off-by: Stephen Warren <swarren@wwwdotorg.org> Acked-by: Arnd Bergmann <arnd@arndb.de>

ARM: soc: soc-specific updates 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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQaO2SAAoJEIwa5zzehBx3TBIQAJYc+vpAqiv8MLQ1XV3cLiIP X57fxM9u1A+uXpXsiCTGR+ga8W4a5tlfGMXDBnl/K2bnFs2x11b9NkFLDJ7mdkih J4c/iOWT/mT5suLnnybyg6ZGaxGkAKou2AumiSmkazmq5hGG67hkpAOqFEfDK0J2 Au7/6VN6GZXgiwt8nYaAB/qR5NVcww4m/6GQ2looaWgRLT/wgC3W2ZKvw6zEdl2J OxOpwf2ujG/75zLQaxTeZ5rKnGtAXH4v0KhY9CWQacQPi4L2MVCrvUrDB4j0as4H Wmsu7g6fZA9Vlf1aW/mlDY1ftozfbDaKORoYVS+CsWhm1oiQI5t+sAWRTkbbS85t pobgKfFdvNsl9kS1zRdEddK2tyotwtXh2jz+P/s1l95hfqZ8IdVBJNMlcrHRINOI 2iQXFfGRhCCqMcfFiGXJ43tYja/aCsaIc4M5TrEma57czZT5jK8HSLh0ZUmFYDoe /TfUegVhFASmkNTk7dVZgZ2UoQVkv4lWs+xuf8YgX3UalWgl/YIRRFl4NnylGlEc jjrX3MjXATqXzLPEZaf8dRZHIpB6FYmZq1QqaoefcUQ46gBOueThElZP3sNWR8a2 MOtknauLfLwQbrcH5CmqKpIpXTB4LKgbf/omH2jQlxBhQ5t7PXHVD1NFsbZbwM8J RVCZb4PwqEwOt/wibTrk =BCp4 -----END PGP SIGNATURE----- Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 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.

arm64: Generic timers support This patch adds support for the ARM generic timers with A64 instructions for accessing the timer registers. It uses the physical counter as the clock source and the virtual counter as sched_clock. The timer frequency can be specified via DT or read from the CNTFRQ_EL0 register. The physical counter is also accessible from user space allowing fast gettimeofday() implementation.
