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>

clocksource: sunxi: Rename sunxi to sun4i During the introduction of the Allwinner SoC platforms, sunxi was initially meant as a generic name for all the variants of the Allwinner SoC. It was ok at the time of the support of only the A10 and A13 that looks pretty much the same, but it's beginning to be troublesome with the future addition of the Allwinner A31 (sun6i) that is quite different, and would introduce some weird logic, where sunxi would actually mean in some case sun4i and sun5i but without sun6i... Moreover, it makes the compatible strings naming scheme not consistent with other architectures, where usually for this kind of compability, we just use the oldest SoC name that has this IP, so let's do just this.

drivers: clocksource: add support for ARM architected timer event stream The ARM architected timer can generate events (used for waking up CPUs executing the wfe instruction) at a frequency represented as a power-of-2 divisor of the clock rate. An event stream might be used: - To implement wfe-based timeouts for userspace locking implementations. - To impose a timeout on a wfe for safeguarding against any programming error in case an expected event is not generated. This patch computes the event stream frequency aiming for a period of 100us between events. It uses ARM/ARM64 specific backends to configure and enable the event stream.

This option enables support for event stream generation based on
the ARM architected timer. It is used for waking up CPUs executing
the wfe instruction at a frequency represented as a power-of-2
divisor of the clock rate.
The main use of the event stream is wfe-based timeouts of userspace
locking implementations. It might also be useful for imposing timeout
on wfe to safeguard against any programming errors in case an expected
event is not generated.
This must be disabled for hardware validation purposes to detect any
hardware anomalies of missing events.
clocksource: arm_global_timer: Add ARM global timer support This is a simple driver for the global timer module found in the Cortex A9-MP cores from revision r1p0 onwards. This should be able to perform the functions of the system timer and the local timer in an SMP system. The global timer has the following features: The global timer is a 64-bit incrementing counter with an auto-incrementing feature. It continues incrementing after sending interrupts. The global timer is memory mapped in the private memory region. The global timer is accessible to all Cortex-A9 processors in the cluster. Each Cortex-A9 processor has a private 64-bit comparator that is used to assert a private interrupt when the global timer has reached the comparator value. All the Cortex-A9 processors in a design use the banked ID, ID27, for this interrupt. ID27 is sent to the Interrupt Controller as a Private Peripheral Interrupt. The global timer is clocked by PERIPHCLK.

Originally, the conversion of all Samsung machines to the new driver was planned for 3.10, but that work ended up being too late and too invasive just before the merge window. Unfortunately, other changes in the Exynos platform resulted in some Exynos4 setups, particularly the Universal C210 board to be broken. In order to fix that with minimum risk, so we now leave the existing pwm clocksource driver in place for all older platforms and use the new driver only for device tree enabled boards.

Notable changes are: * We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no longer used. (Uwe Kleine-König) * The Qualcomm MSM platform is split out into legacy mach-msm and new-style mach-qcom, to allow easier maintainance of the new hardware support without regressions. (Kumar Gala) * A rework of some of the Kconfig logic to simplify multiplatform support (Rob Herring) * Samsung Exynos gets closer to supporting multiplatform (Sachin Kamat and others) * mach-bcm3528 gets merged into mach-bcm (Stephen Warren) * at91 gains some common clock framework support (Alexandre Belloni, Jean-Jacques Hiblot and other French people). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAUz/yOWCrR//JCVInAQLOPBAAwTMkMrD8S8ggz6vfiQHZNdRPAC7NUJ46 +eYKmBVi5d6EdnjNuRElWENsh0ZosSAUFHrXsIC2NdH9sAJ9HOqWNNLymuA59Jo9 HZ/Ze6xQXDPNV7TROPoXuIli/2OCOXyyQHJsfI7h9V3PCx31qo0B5OdCxU0mtXK6 r1giREhnJFwfQMF/FTdnzhalFJoSjWwv/nkpNmQDJKRLKj9GzwQqItqw68gV6RzU Gnt6YK+9xC1B0cfWTFhAm6kbr9i7mvHoMG5tE3no2uuJMn4K7TgeMqOyvPWhmUeB EZi656szT1m5VfRWOqG+7coZO2VM4GO4NI0Xfin3GHllugOYls1il/FAfCPMLiwh RvuOmQGCkLIpdkuHop5QaI/h1EzlHA59nzTjmGf1+wWPsm0CIg08XOD9izQbRnN9 EmRqn1/8POIi17xcWyeMp8LB0APsTI+IflZFaYprEY9VlLLA/Pd+7udULhs8Bq8y 1l6fB6aPZKnDKCBy/PEIR+y+EHFEbwfrx6zm/pxVDX6P5DlQMFWL78pdBoJUa2h8 3pm/bSzNU5OSz1nJMLJv2jBTtnM5BvFgQBUi2qJ9Lr+nUhJXKCJ80kE/nOlXoCIU J952p3OhkYTQQcjuUVQeTXvRUOGB7mKok0pDFZNE6c7faqxTCudMABQq/KbMFstU eE3cH5FyYj4= =GcBb -----END PGP SIGNATURE----- Merge tag 'cleanup-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Arnd Bergmann: "These cleanup patches are mainly move stuff around and should all be harmless.
