Merge branch 'ux500-devicetree-for-arm-soc' of... 

Merge branch 'ux500-devicetree-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/dt

Linus Walleij <linus.walleij@linaro.org> writes:

  this pull request contains some device tree work by Lee Jones.
  I have tried to keep these patches in the arch/arm/boot/dts/*
  space to get some sanity in the branch proliferation.

  There is still one patch that touches arch/arm/mach-ux500 too
  though (but it should merge fine with the other ux500 stuff).

  The changes to the device tree are of course dependent on some
  core changes and some patching in the GPIO/pin driver, but as
  the device tree files are believed to be a different world
  (and should one day live in their own git) I split this off
  anyway. I don't think people bisect the device trees per se
  and the board code in conjunction anyway.

Nomadik GPIO controller



Required properties:

- compatible            : Should be "st,nomadik-gpio".

- reg                   : Physical base address and length of the controller's registers.

- interrupts            : The interrupt outputs from the controller.

- #gpio-cells           : Should be two:

                            The first cell is the pin number.

                            The second cell is used to specify optional parameters:

                              - bits[3:0] trigger type and level flags:

                                  1 = low-to-high edge triggered.

                                  2 = high-to-low edge triggered.

                                  4 = active high level-sensitive.

                                  8 = active low level-sensitive.

- gpio-controller       : Marks the device node as a GPIO controller.

- interrupt-controller  : Marks the device node as an interrupt controller.

- gpio-bank             : Specifies which bank a controller owns.

- st,supports-sleepmode : Specifies whether controller can sleep or not



Example:



                gpio1: gpio@8012e080 {

                        compatible = "st,nomadik-gpio";

                        reg =  <0x8012e080 0x80>;

                        interrupts = <0 120 0x4>;

                        #gpio-cells = <2>;

                        gpio-controller;

                        interrupt-controller;

                        supports-sleepmode;

                        gpio-bank = <1>;

                };
