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. * 'ux500-devicetree-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson: ARM: ux500: Configure the PRCMU Timer for db8500 based devices in DT ARM: ux500: Enable the SMSC9115 on Snowball via Device Tree drivers/gpio: represent gpio-nomadik as an IRQ controller in DT documentation ARM: ux500: Rename gpio_keys in the Device Tree file drivers/gpio: gpio-nomadik: Provide documentation for Device Tree bindings drivers/gpio: gpio-nomadik: Device Tree bindings ARM: ux500: Enable the external bus with Device Tree ARM: ux500: Shorten Snowball's DT compatible gpio entry ARM: ux500: Rename the DT compatible entry for i2c devices on Snowball Signed-off-by: Arnd Bergmann <arnd@arndb.de> [olof: rebuilt branch due to drop of an early merge] Signed-off-by: Olof Johansson <olof@lixom.net>

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
|
||||
|
||||
