Pull ARM SoC driver changes from Arnd Bergmann:
 "These changes are mostly for ARM specific device drivers that either
  don't have an upstream maintainer, or that had the maintainer ask us
  to pick up the changes to avoid conflicts.

  A large chunk of this are clock drivers (bcm281xx, exynos, versatile,
  shmobile), aside from that, reset controllers for STi as well as a
  large rework of the Marvell Orion/EBU watchdog driver are notable"

gpio: pl061: convert driver to use gpiolib irqchip

2014-03-26T09:31:33+00:00

This converts the PL061 driver to register its chained irq
handler and irqchip using the helpers in the gpiolib core.

gpio: add IRQ chip helpers in gpiolib

2014-03-26T09:31:21+00:00

This provides a function gpiochip_irqchip_add() to set
up an irqchip for a GPIO controller, and a function
gpiochip_set_chained_irqchip() to chain it to a parent
irqchip.

Most GPIOs are of the type where a number of lines form
a cascaded interrupt controller chained onto
the primary system interrupt controller (or further down the
chain) so let's add this helper and factor the code to
request the lines to be used as IRQs, the .to_irq() function
and the irqdomain into the core as well.

gpio: Driver for SYSCON-based GPIOs

2014-03-18T08:28:31+00:00

SYSCON driver was designed for using memory areas (registers)
that are used in several subsystems. There are systems (CPUs)
which use bits in one register for various purposes and thus
should be handled by various kernel subsystems. This driver
allows you to use the individual SYSCON bits as GPIOs.
ARM CLPS711X SYSFLG1 input lines has been added as first user
of this driver.

depend on ARM && OF_GPIO.

gpio: add a driver for the Synopsys DesignWare APB GPIO block

2014-03-05T00:59:45+00:00

The Synopsys DesignWare block is used in some ARM devices (picoxcell)
and can be configured to provide multiple banks of GPIO pins.

v12: - Add irq_startup/shutdown
     - do irq_create_mapping() in probe, irq_find_mapping() in to_irq()
     - Adjust mappings to show support for 1 gpio per port.
     - gpio-cells = <1>
v11: - Use NULL when checking existence of 'interrupts' property
     - Bindings descriptions cleanup
v10: - in documentation nr-gpio -> nr-gpios
v9:  - cleanup in dt bindings doc
     - use of_get_child_count()
v8:  - remove socfpga.dtsi changes
     - minor cleanup in devicetree documentation
v7:  - use irq_generic_chip
     - support one irq per gpio line or one irq for many
     - s/bank/port/ and other cleanup
v6:  - (atull) squash the set of patches
     - use linear irq domain
     - build fixes. Original driver was reviewed on v3.2.
     - Fix setting irq edge type for 'rising' and 'both'.
     - Support as a loadable module.
     - Use bgpio_chip's spinlock during register access.
     - Clean up register names to match spec
     - s/bank/port/ because register names use the word 'port'
     - s/nr-gpio/nr-gpios/
     - don't get/put the of_node
     - remove signoffs/acked-by's because of changes
     - other cleanup
v5:  - handle sparse bank population correctly
v3:  - depend on rather than select IRQ_DOMAIN
     - split IRQ support into a separate patch
v2:  - use Rob Herring's irqdomain in generic irq chip patches
     - use reg property to indicate bank index
     - support irqs on both edges based on LinusW's u300 driver
