clocksource/drivers/tegra: Allow timer irq affinity change

2015-12-15T08:41:06Z

Allow the timer core to change the smp affinity of the broadcast timer irq by setting CLOCK_EVT_FEAT_DYNIRQ flag. This reduces interrupt pressure and wakeups on CPU0 as well as vastly reducing the number of timer broadcast IPIs. Signed-off-by: Lucas Stach Signed-off-by: Daniel Lezcano

clockevents/drivers/tegra20: Migrate to new 'set-state' interface

2015-08-10T09:40:40Z

Migrate tegra20 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED.

ARM, clocksource/drivers: Provide read_boot_clock64() and read_persistent_clock64() and use them

2015-04-03T06:18:23Z

As part of addressing "y2038 problem" for in-kernel uses, this patch converts read_boot_clock() to read_boot_clock64() and read_persistent_clock() to read_persistent_clock64() using timespec64 by converting clock_access_fn to use timespec64.

clocksource/drivers/tegra: Provide y2038-safe tegra_read_persistent_clock() replacement

2015-04-03T06:18:22Z

As part of addressing "y2038 problem" for in-kernel uses, this patch adds the y2038-safe tegra_read_persistent_clock64() using timespec64. Because we rely on some subsequent changes to convert arm multiarch support, tegra_read_persistent_clock() will be removed then.

clocksource: tegra: Use us counter as delay timer

2014-06-16T18:48:12Z

All Tegra SoCs have a freerunning microsecond counter which can be used as a delay timer. Signed-off-by: Peter De Schrijver Acked-by: Russell King Signed-off-by: Stephen Warren

clocksource: tegra: Remove deprecated IRQF_DISABLED

2013-12-11T10:40:28Z

This patch removes the use of the IRQF_DISABLED flag. It's a NOOP since 2.6.35 and it will be removed one day. [dlezcano] : slightly changed the changelog Signed-off-by: Michael Opdenacker Signed-off-by: Daniel Lezcano

clocksource: Put nodes passed to CLOCKSOURCE_OF_DECLARE callbacks centrally

2013-10-02T09:42:48Z

Instead of letting each driver call of_node_put do it centrally in the loop that also calls the CLOCKSOURCE_OF_DECLARE callbacks. This is less prone to error and also moves getting and putting the references into the same function. Consequently all respective of_node_put calls in drivers are removed.

clocksource: tegra: Switch to sched_clock_register()

2013-07-30T18:24:54Z

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. Cc: Stephen Warren Acked-by: Stephen Warren Tested-by: Stephen Warren Signed-off-by: Stephen Boyd Signed-off-by: John Stultz

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.
