Add a binding for the arm architected timer hardware's memory
mapped interface. The mmio timer hardware is made up of one base
frame and a collection of up to 8 timer frames, where each of the
8 timer frames can have either one or two views. A frame
typically maps to a privilege level (user/kernel, hypervisor,
secure). The first view has full access to the registers within a
frame, while the second view can be restricted to particular
registers within a frame. Each frame must support a physical
timer. It's optional for a frame to support a virtual timer.

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.

Previously, the code was using a specific DT bindings.
As now OMAP supports the standard way to model GPIOs,
there is no point in having a ti specific binding.

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.

The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT
keyboard, yet they do not have a hardware PS/2 controller. Instead, a
firmware runs on a dedicated core ("Security Processor", part of the SoC)
that acts as a PS/2 controller through bit-banging.

Communication between the main cpu (Application Processor) and the
Security Processor happens via a standard command mechanism implemented
by the SoC. Add a driver for this interface to enable keyboard/mouse
input on this platform.

Add compatible property for the Exynos5250 and enable the frame start
and frame end interrupts. These interrupts are needed for the Exynos5
FIMC-IS firmware. The driver enables those interrupt only where available,
depending on the 'compatible' property. This can be optimized further,
by exposing some API at the subdev driver, so the host driver can enable
extra interrupts only for the image processing chains involving FIMC-IS.

This patch adds support for the Exynos5250 SoC variant of the FIMC-LITE
IP. A 'compatible' string is added for Exynos5250 compatible devices
and the capture DMA handling is reworked to use the FLITE_REG_CIFCNTSEQ
register, masking output DMA buffer address slots. The frame interrupt
is enabled so there are now 2 interrupts per frame. This likely can be
optimized in future by using any status registers that allow to figure
out what the last and the currently written frame buffer is. It would
also be more reliable in cases where there are high interrupt service
latencies.
