2013-11-14pinctrl: single: call pcs_soc->rearm() whenever IRQ mask is changedRoger Quadros
On OMAPs the IO ring must be rearmed each time the pad wakeup configuration is changed. So call pcs_soc->rearm() from pcs_irq_set(). As pinctrl-single is now an interrupt controller in some cases, we should follow the standards and keep the interrupts enabled constantly, and not just for wake-up events. The tracking of runtime vs wake-up interrupts can be handled separately for the automated runtime PM solution when we have it in the future.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO changes from Linus Walleij: "Here is the bulk of GPIO changes for the v3.13 development cycle. I've got ACKs for the things that affect other subsystems (or it's my own subsystem, like pinctrl). Most of that pertain to an attempt from my side to consolidate and get rid of custom GPIO implementations in the ARM tree. I will continue doing this. The main change this time is the new GPIO descriptor API, background for this can be found in Corbet's summary from this january in LWN: http://lwn.net/Articles/533632/ Summary: - Merged the GPIO descriptor API from Alexandre Courbot. This is a first step toward trying to get rid of the global GPIO numberspace for the future. - Add an API so that driver can flag that a certain GPIO line is being used by a irqchip backend for generating IRQs, so that we can enforce checks, like not allowing users to switch that line to an output at runtime, since this makes no sense. Implemented corresponding calls in a few select drivers. - ACPI GPIO cleanups, refactorings and switch to using the descriptor-based interface. - Support for the TPS80036 Palmas GPIO variant. - A new driver for the Broadcom Kona GPIO SoC IP block. - Device tree support for the PCF857x driver. - A set of ARM GPIO refactorings with the goal of getting rid of a bunch of custom GPIO implementations from the arch/arm/* tree: * Move the IOP GPIO driver to the GPIO subsystem and fix all users to use the gpiolib API for accessing GPIOs. Delete the old custom GPIO implementation. * Delete the unused custom PXA GPIO implemention. * Convert all users of the IXP4 custom GPIO implementation to use gpiolib and delete the custom implementation. * Delete the custom Gemini GPIO implementation, also completely unused. - Various cleanups and renamings" * tag 'gpio-v3.13-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (85 commits) gpio: gpio-mxs: Remove unneeded dt checks gpio: pl061: don't depend on CONFIG_ARM gpio: bcm-kona: add missing .owner to struct gpio_chip gpiolib: provide a declaration of seq_file in gpio/driver.h gpiolib: include gpio/consumer.h in of_gpio.h for desc_to_gpio() gpio: provide stubs for devres gpio functions gpiolib: devres: add missing headers gpiolib: make GPIO_DEVRES depend on GPIOLIB gpiolib: devres: fix devm_gpiod_get_index() gpiolib / ACPI: document the GPIO descriptor based interface gpiolib / ACPI: allow passing GPIOF_ACTIVE_LOW for GpioInt resources gpiolib / ACPI: add ACPI support for gpiod_get_index() gpiolib / ACPI: convert to gpiod interfaces gpiolib: add gpiod_get() and gpiod_put() functions gpiolib: port of_ functions to use gpiod gpiolib: export descriptor-based GPIO interface Fixup "MAINTAINERS: GPIO-INTEL-MID: add maintainer" gpio: bcm281xx: Don't print addresses of GPIO area in probe() gpio: tegra: use new gpio_lock_as_irq() API gpio: rcar: Include linux/of.h header ...

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 ...

2013-10-16pinctrl: rockchip: emulate both edge triggered interruptsHeiko Stübner

2013-10-16pinctrl: rockchip: add rk3188 specificsHeiko Stübner
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.

2013-10-16pinctrl: rockchip: separate different sub-types moreHeiko Stübner
Further investigation of the different Rockchip SoCs showed that the differences especially in the pull settings are quite deep. As further patches will show, the register layout for the pulls of the rk3188 is quite strange. Also it is to assume, that later Rockchip SoCs may introduce even more quirks in this regard, making it hard to support all of those using the current generic pull_* variables. Therefore move the driver to hold the type of controller in an enum and do the handling according to it in the necessary places. Also instead of calculating the register in the get and set pull functions move it to a type-specific callback.

2013-10-10pinctrl: single: Add support for auxdataTony Lindgren
For omaps, we still have dependencies to the legacy code for handling the PRM (Power Reset Management) interrupts, and also for reconfiguring the io wake-up chain after changes. Let's pass the PRM interrupt and the rearm functions via auxdata. Then when at some point we have a proper PRM driver, we can get the interrupt via device tree and set up the rearm function as exported function in the PRM driver. By using auxdata we can remove a dependency to the wake-up events for converting omap3 to be device tree only.

2013-10-10pinctrl: single: Add support for wake-up interruptsTony Lindgren
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 <linus.walleij@linaro.org>. 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.

2013-10-08pinctrl: remove redundant of_match_ptrSachin Kamat
The data structure of_match_ptr() protects is always compiled in. Hence of_match_ptr() is not needed.
