Pull pin control updates from Linus Walleij: "Main pin control pull request for the v3.13 cycle. The changes hitting arch/blackfin are ACKed by the Blackfin maintainer, and the device tree bindings are ACKed to the extent possible by someone from the device tree maintainers group. - Blackfin ADI pin control driver, we move yet another architecture under this subsystem umbrella. - Incremental updates to the Renesas Super-H PFC pin control driver. New subdriver for the r8a7791 SoC. - Non-linear GPIO ranges from the gpiolib side of things, this enabled simplified device tree bindings by referring entire groups of pins on some pin controller to act as back-end for a certain GPIO-chip driver. - Add the Abilis TB10x pin control driver used on the ARC architecture. Also the corresponding GPIO driver is merged through this tree, so the ARC has full support for pins and GPIOs after this. - Subdrivers for Freescale i.MX1, i.MX27 and i.MX50 pin controller instances. The i.MX1 and i.MX27 is an entirely new family (silicon) of controllers whereas i.MX50 is a variant of the previous supported controller. - Then the usual slew of fixes, cleanups and incremental updates" The ARC DT changes are apparently still pending, that hopefully gets sorted out in a timely manner. * tag 'pinctrl-for-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl: (48 commits) pinctrl: imx50: add pinctrl support code for the IMX50 SoC pinctrl: at91: copy define to driver pinctrl: remove minor dead code pinctrl: imx: fix using pin->input_val wrongly pinctrl: imx1: fix return value check in imx1_pinctrl_core_probe() gpio: tb10x: fix return value check in tb10x_gpio_probe() gpio: tb10x: use module_platform_driver to simplify the code pinctrl: imx27: imx27 pincontrol driver pinctrl: imx1 core driver pinctrl: sh-pfc: r8a7791 PFC support sh-pfc: r8a7778: Add CAN pin groups gpio: add TB10x GPIO driver pinctrl: at91: correct a few typos pinctrl: mvebu: remove redundant of_match_ptr pinctrl: tb10x: use module_platform_driver to simplify the code pinctrl: tb10x: fix the error handling in tb10x_pinctrl_probe() pinctrl: add documentation for pinctrl_get_group_pins() pinctrl: rockchip: emulate both edge triggered interrupts pinctrl: rockchip: add rk3188 specifics pinctrl: rockchip: remove redundant check ...

pinctrl: rockchip: add rk3188 specifics

2013-10-16T13:33:54Z

Besides the pull registers sitting in a separate place, the rk3188 also has the peculiarity that the pull registers of the first bank are split and the first half is sitting in the register space of the pmu. Therefore this adds a special bank-type for the first bank, to handle the two register sources. Signed-off-by: Heiko Stuebner Signed-off-by: Linus Walleij

pinctrl: single: Add support for wake-up interrupts

2013-10-10T22:30:30Z

The pin control registers can have interrupts for example for device wake-up. These interrupts can be treated as a chained interrupt controller as suggested earlier by Linus Walleij . This patch adds support for interrupts in a way that should be pretty generic, and works for the omaps that support wake-up interrupts. On omaps, there's an interrupt enable and interrupt status bit for each pin. The two pinctrl domains on omaps share a single interrupt from the PRM chained interrupt handler. Support for other similar hardware should be easy to add. Note that this patch does not attempt to handle the wake-up interrupts automatically unlike the earlier patches. This patch allows the device drivers to do a request_irq() on the wake-up pins as needed. I'll try to do also a separate generic patch for handling the wake-up events automatically. Also note that as this patch makes the pinctrl-single an irq controller, the current bindings need some extra trickery to use interrupts from two different interrupt controllers for the same driver. So it might be worth waiting a little on the patches enabling the wake-up interrupts from drivers as there should be a generic way to handle it coming. And also there's been discussion of interrupts-extended binding for using interrupts from multiple interrupt controllers. In any case, this patch should be ready to go allowing handling the wake-up interrupts in a generic way, or separately from the device drivers.

pinctrl: imx: update fsl,pins description in bindings doc

2013-10-09T12:42:36Z

While commit e164153 (pinctrl: imx: move hard-coding data into device tree) moves to use DTC macro for imx pinctrl device tree setting, it changes the semantics of fsl,pins without updating the bindings doc properly. Let's update the fsl,pins description to stop confusing people. While at it, the example in the document is updated, and the stale TODO gets removed.

ARM: dts: mxs: add pinctrl header files

2013-09-26T05:01:36Z

Remove the list of possible pin configurations from the documentation file and create header files containing those definitions. This eliminates the need for error-prone manual lookup of those values in the documentation and guarantees consistency between the human readable representation of the pad function in the .dts file and the actual binary value used in DT.
