ARM: 8366/1: move Dual-Timer SP804 driver to drivers/clocksource

2015-06-02T08:58:18Z

The ARM Dual-Timer SP804 module is peripheral found not only on ARM32 platforms but also on ARM64 platforms. This patch moves the driver out of arch/arm to driver/clocksource so that it can be used on ARM64 platforms also.

ARM: 8365/1: introduce sp804_timer_disable and remove arm_timer.h inclusion

2015-06-02T08:58:18Z

The header asm/hardware/arm_timer.h is included in various machine specific files to access TIMER_CTRL and initialise to a known state. This patch introduces a new function sp804_timer_disable to disable the SP804 timers and uses the same for initialising the timers to known(off) state, thereby removing the dependency on the header asm/hardware/arm_timer.h This change is in prepartion to move sp804 timer support out of arch/arm so that it can be used on ARM64 platforms.

ARM: timer-sp: allow getting timer1 clock from DT to fallback to legacy clock

2014-06-24T19:16:03Z

The sp804 clocks may be specified in DT, but the kernel may still be using legacy clocks. This is handled if a single clock for sp804 is present, but not when 3 clocks are present. This prevents Versatile platforms from breaking when the DT has clocks added. Signed-off-by: Rob Herring Cc: Russell King

ARM: SP804: make Integrator/CP timer pick clock from DT

2014-02-13T10:20:36Z

This modifies the SP804 driver so that the clock will be taken from the device tree node for the timer. Cc: Russell King Cc: Rob Herring Signed-off-by: Linus Walleij

ARM: timer-sp: Switch to sched_clock_register()

2013-11-21T23:40:59Z

The 32 bit sched_clock interface now supports 64 bits. Upgrade to the 64 bit function to allow us to remove the 32 bit registration interface. Also mark the read function notrace since we're here and failure to do so would cause ftrace to break. Cc: Russell King Signed-off-by: Stephen Boyd Signed-off-by: Kevin Hilman

ARM: 7856/1: timer-sp: remove deprecated IRQF_DISABLED

ARM: timer-sp: Set dynamic irq affinity

2013-08-21T22:18:53Z

When a cpu goes to a deep idle state where its local timer is shutdown, it notifies the time frame work to use the broadcast timer instead. Unfortunately, the broadcast device could wake up any CPU, including an idle one which is not concerned by the wake up at all. This implies, in the worst case, an idle CPU will wake up to send an IPI to another idle cpu. This patch fixes this for ARM platforms using timer-sp, by setting CLOCK_EVT_FEAT_DYNIRQ feature.

sched_clock: Make ARM's sched_clock generic for all architectures

2013-06-12T21:02:13Z

Nothing about the sched_clock implementation in the ARM port is specific to the architecture. Generalize the code so that other architectures can use it by selecting GENERIC_SCHED_CLOCK.

ARM: integrator-cp: convert use CLKSRC_OF for timer init

2013-04-11T20:11:21Z

Move the integrator-cp timer init to timer-sp.c and use CLKSRC_OF. There is no reason to use the aliases, so drop them from the init code. The integrator-cp timers are mistakenly called sp804 timers in the dts, but in fact they are not sp804 dual timers, but single timers with the same programming model. Fix the dts to reflect this.
