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

2015-08-10T09:40:40+00:00

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

2015-04-03T06:18:23+00:00

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

2015-04-03T06:18:22+00:00

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

All Tegra SoCs have a freerunning microsecond counter which can be used as a
delay timer.

clocksource: tegra: Remove deprecated IRQF_DISABLED

2013-12-11T10:40:28+00:00

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.

clocksource: Put nodes passed to CLOCKSOURCE_OF_DECLARE callbacks centrally

2013-10-02T09:42:48+00:00

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()

2013-07-30T18:24:54+00:00

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.

sched_clock: Make ARM's sched_clock generic for all architectures

2013-06-12T21:02:13+00:00

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.

Merge tag 'tegra-for-3.10-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/cleanup

2013-04-09T13:27:52+00:00

From Stephen Warren :

ARM: tegra: cleanup

This branch includes various cleanup of the core Tegra support.

* Unification of the separate board-dt-tegra*.c files into a single
  tegra.c, now that everything is DT-driven and basically identical.
* Use of_clk_get() in the Tegra clocksource driver so that clocks are
  described in DT rather than hard-coding clock names.
* Some cleanup of the PMC-related code, with the aim that the PMC
  "driver" contains more of the code that touches PMC registers, rather
  than spreading PMC register accesses through other files.
* Conversion of the "PMC" driver to acquire resources describe in device
  tree rather than hard-coding them.
* Use of common code for the CPU sleep TLB invalidation.

This branch is based on the previous fixes pull request.

* tag 'tegra-for-3.10-cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
  ARM: tegra: use setup_mm_for_reboot rather than explicit pgd switch

  ARM: tegra: pmc: add power on function for secondary CPUs
  ARM: tegra: pmc: convert PMC driver to support DT only
  ARM: tegra: fix the PMC compatible string in DT
  ARM: tegra: pmc: add specific compatible DT string for Tegra30 and Tegra114
