Pull ARM SoC platform changes from Olof Johansson:
"New core SoC-specific changes.

New platforms:
* Introduction of a vendor, Hisilicon, and one of their SoCs with
some random numerical product name.
* Introduction of EFM32, embedded platform from Silicon Labs (ARMv7m,
i.e. !MMU).
* Marvell Berlin series of SoCs, which include the one in Chromecast.
* MOXA platform support, ARM9-based platform used mostly in
industrial products
* Support for Freescale's i.MX50 SoC.

Other work:
* Renesas work for new platforms and drivers, and conversion over to
more multiplatform-friendly device registration schemes.
* SMP support for Allwinner sunxi platforms.
* ... plus a bunch of other stuff across various platforms"

rename ARCH_BCM to ARCH_BCM_MOBILE (clocksource)

2013-12-13T16:36:22+00:00

Currently ARCH_BCM has been used for Broadcom
Mobile V7 based SoCs. In order to allow other Broadcom
SoCs to also use mach-bcm directory and files, this patch
renames the original ARCH_BCM to ARCH_BCM_MOBILE, and
uses ARCH_BCM to define any Broadcom chip residing
in mach-bcm directory.

clocksource: Add Allwinner SoCs HS timers driver

2013-12-11T10:37:50+00:00

Most of the Allwinner SoCs (at this time, all but the A10) also have a
High Speed timers that are not using the 24MHz oscillator as a source
but rather the AHB clock running much faster.

The IP is slightly different between the A10s/A13 and the one used in
the A20/A31, since the latter have 4 timers available, while the former
have only 2 of them.

ARM: clocksource: Add support for MOXA ART SoCs

2013-07-18T13:27:47+00:00

This patch adds an clocksource driver for the main timer(s)
found on MOXA ART SoCs.

The MOXA ART SoC provides three separate timers with individual
count/load/match registers, two are used here:

TIMER1: clockevents, used to support oneshot and periodic events
TIMER2: set up as a free running counter, used as clocksource

Timers are preconfigured by bootloader to count down and interrupt
on match or zero. Count increments every APB clock cycle and is
automatically reloaded when it reaches zero.

clocksource: arm_global_timer: Add ARM global timer support

2013-07-03T15:30:57+00:00

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.

clocksource: Add Marvell Orion SoC timer

2013-07-02T13:01:45+00:00

This patch add a DT enabled driver for timers found on Marvell Orion SoCs
(Kirkwood, Dove, Orion5x, and Discovery Innovation). It installs a free-
running clocksource on timer0 and a clockevent source on timer1.
Corresponding device tree documentation is also added.

clocksource: Add generic dummy timer driver

2013-06-24T20:27:37+00:00

Several architectures have a dummy timer driver tightly coupled with
their broadcast code to support machines without cpu-local timers (or
where there is a lack of driver support).

Since 12ad100046: "clockevents: Add generic timer broadcast function"
it's been possible to write broadcast-capable timer drivers decoupled
from the broadcast mechanism. We can use this functionality to implement
a generic dummy timer driver that can be shared by all architectures
with generic tick broadcast (ARCH_HAS_TICK_BROADCAST).

This patch implements a generic dummy timer using this facility.

clocksource: Add TI-Nspire timer support

2013-06-06T15:23:13+00:00

This patch adds a clocksource/clockevent driver for the timer found on some
models in the TI-Nspire calculator series. The timer has two 16bit subtimers
within its memory mapped I/O interface but only the first can generate
interrupts. The first subtimer is used to generate clockevents but only if an
interrupt number and register is given.

The interrupt acknowledgement mechanism is a little strange because the
interrupt mask and acknowledge registers are located in another memory mapped
I/O peripheral. The address of this register is passed to the driver through
device tree bindings.

The second subtimer is used as a clocksource because it isn't capable of
generating an interrupt. This subtimer is always added.
