Stephen Warren 6bb27d7349 ARM: delete struct sys_timer
Now that the only field in struct sys_timer is .init, delete the struct,
and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:
http://www.spinics.net/lists/arm-kernel/msg203686.html

Includes mach-omap2 fixes from Igor Grinberg.

Linus Torvalds 8287361abc ARM: arm-soc: Header cleanups
This is a collection of header file cleanups, mostly for OMAP and AT91,
 that keeps moving the platforms in the direction of multiplatform by
 removing the need for mach-dependent header files used in drivers and
 other places.

  multiplatform by removing the need for mach-dependent header files
  used in drivers and other places."

Fix up mostly trivial conflicts as per Olof.

This patch adds the support for new PIO controller found on some
at91sam SOCs.
- more peripheral multiplexing
- more features to configure on a PIO (pull-down, Schmitt trigger, debouncer)
- support for several IRQ triggering features (type and polarity)

Support for those new features are retrieved from the device tree
compatibility string.

Debugfs at91_gpio file is updated to monitor configuration.

Nicolas Ferre 8014d6f4dd ARM: at91: AIC and GPIO IRQ device tree initialization
Both AIC and GPIO controllers are now using the standard of_irq_init()
function to initialize IRQs in case of DT use.
The DT specific initialization functions are now separated from the
non-DT case and are now using "linear" irq domains.
The .map() irqdomain operation is responsible for positioning the IRQ
handlers. In AIC case, the Linux IRQ number is directly programmed in
the hardware to avoid an additional reverse mapping operation.
The AIC position its irq domain as the "default" irq domain.

For DT case, the priority is not yet filled in the SMR. It will be the
subject of another patch.

Nicolas Ferre 49fe2ba313 ARM: at91: dt: at91sam9g45 family and board device tree files
Create a new device tree source file for Atmel at91sam9g45 SoC family.
The Evaluation Kit at91sam9m10g45ek includes it.
This first basic support will be populated as drivers and boards will be
converted to device tree.
Contains serial, dma and interrupt controllers.

The generic board file still takes advantage of platform data for early serial
init. As we need a storage media and the NAND flash driver is not converted to
DT yet, we keep old initialization for it.
