clocksource: tegra: Use us counter as delay timer

2014-06-16T18:48:12+00:00

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: replace the CPU power on function with PMC call
  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
  ARM: tegra: refactor tegra{20,30}_boot_secondary
  clocksource: tegra: move to of_clk_get
  ARM: tegra: Unify Device tree board files
  ARM: tegra: Rename board-dt-tegra20.c to tegra.c
  ARM: tegra: Unify tegra{20,30,114}_init_early()

clocksource: tegra: move to of_clk_get

2013-03-11T20:29:43+00:00

The new clockframework introduced DT IDs for each clock. To be able to remove
the device registrations, this driver needs to be updated to use the DT IDs.
Note that the actual removal of the clk_register_clkdev() calls will be done
in a later series.

ARM: smp_twd: convert to use CLKSRC_OF init

2013-03-11T13:42:08+00:00

Now that we have OF based init with CLKSRC_OF, convert smp_twd init
function to use it and covert all callers of
twd_local_timer_of_register.

clocksource: tegra20: use the device_node pointer passed to init

2013-03-11T13:42:07+00:00

We've already matched the node, so use the node pointer passed in. The rtc
init was intermingled with the timer init, so split this out to a separate
init function.

clocksource: pass DT node pointer to init functions

2013-03-11T13:42:07+00:00

In cases where we have multiple nodes of the same type, we may need the
node pointer to know which node was matched. Passing the node pointer
also keeps the init function from having to match the node a 2nd time.

Update bcm2835, vt8500, and tegra20 init functions for the new function
prototype. Further tegra20 clean-ups are in follow-up commit.
