2016-08-22pinctrl: cherryview: Do not mask all interrupts in probeMika Westerberg1-3/+2
The Cherryview GPIO controller has 8 or 16 wires connected to the I/O-APIC which can be used directly by the platform/BIOS or drivers. One such wire is used as SCI (System Control Interrupt) which ACPI depends on to be able to trigger GPEs (General Purpose Events). The pinctrl driver itself uses another IRQ resource which is wire OR of all the 8 (or 16) wires and follows what BIOS has programmed to the IntSel register of each pin. Currently the driver masks all interrupts at probe time and this prevents these direct interrupts from working as expected. The reason for this is that some early stage prototypes had some pins misconfigured causing lots of spurious interrupts. We fix this by leaving the interrupt mask untouched. This allows SCI and other direct interrupts work properly. What comes to the possible spurious interrupts we switch the default handler to be handle_bad_irq() instead of handle_simple_irq() (which was not correct anyway).

2016-08-22pinctrl: meson: get rid of unneeded domain structuresBeniamino Galvani5-228/+118
The driver originally supported more domains (register ranges) per pinctrl device, but since commit 9dab1868ec0d ("pinctrl: amlogic: Make driver independent from two-domain configuration") each device gets assigned a single domain and we instantiate multiple pinctrl devices in the DT. Therefore, now the 'meson_domain' and 'meson_domain_data' structures don't have any reason to exist and can be removed to make the model simpler to understand. This commit doesn't change behavior.

2016-08-11pinctrl: qcom: Add generic ssbi and spmi GPIO/MPP bindingsStephen Boyd2-0/+2
The drivers don't really need to know which PMIC they're for, so make a generic binding for them. This alleviates us from updating the drivers every time a new PMIC comes out. It's still recommended that we update the binding with new PMIC models and always specify the specific model for the MPPs and gpios before the generic compatible string in devicetree, but this at least cuts down on adding more and more compatible strings to the drivers until we actually need them.

The patches are tested in linux-next for some time, patches to other subsystem mostly have ACKs. I got overly ambitious with configureing lines as input for IRQ lines but it turns out that some controllers have their interrupt-enable and input-enabling in orthogonal settings so the assumption that all IRQ lines are input lines does not hold. Oh well, revert and back to the drawing board with that. Core changes: - The big item is of course the completion of the character device ABI. It has now replaced and surpassed the former unmaintainable sysfs ABI: we can now hammer (bitbang) individual lines or sets of lines and read individual lines or sets of lines from userspace, and we can also register to listen to GPIO events from userspace. As a tie-in we have two new tools in tools/gpio: gpio-hammer and gpio-event-mon that illustrate the proper use of the new ABI. As someone said: the wild west days of GPIO are now over. - Continued to remove the pointless ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB Kconfig symbols. I'm patching hexagon, openrisc, powerpc, sh, unicore, ia64 and microblaze. These are either ACKed by their maintainers or patched anyways after a grace period and no response from maintainers. Some archs (ARM) come in from their trees, and others (x86) are still not fixed, so I might send a second pull request to root it out later in this merge window, or just defer to v4.9. - The GPIO tools are moved to the tools build system. New drivers: - New driver for the MAX77620/MAX20024. - New driver for the Intel Merrifield. - Enabled PCA953x for the TI PCA9536. - Enabled PCA953x for the Intel Edison. - Enabled R8A7792 in the RCAR driver. Driver improvements: - The STMPE and F7188x now supports the .get_direction() callback. - The Xilinx driver supports setting multiple lines at once. - ACPI support for the Vulcan GPIO controller. - The MMIO GPIO driver supports device tree probing. - The Acer One 10 is supported through the _DEP ACPI attribute. Cleanups: - A major cleanup of the OF/DT support code. It is way easier to read and understand now, probably this improves performance too. - Drop a few redundant .owner assignments. - Remove CLPS711x boardfile support: we are 100% DT" * tag 'gpio-v4.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (67 commits) MAINTAINERS: Add INTEL MERRIFIELD GPIO entry gpio: dwapb: add missing fwnode_handle_put() in dwapb_gpio_get_pdata() gpio: merrifield: Protect irq_ack() and gpio_set() by lock gpio: merrifield: Introduce GPIO driver to support Merrifield gpio: intel-mid: Make it depend to X86_INTEL_MID gpio: intel-mid: Sort header block alphabetically gpio: intel-mid: Remove potentially harmful code gpio: rcar: add R8A7792 support gpiolib: remove duplicated include from gpiolib.c Revert "gpio: convince line to become input in irq helper" gpiolib: of_find_gpio(): Don't discard errors gpio: of: Allow overriding the device node gpio: free handles in fringe cases gpio: tps65218: Add platform_device_id table gpio: max77620: get gpio value based on direction gpio: lynxpoint: avoid potential warning on error path tools/gpio: add install section tools/gpio: move to tools buildsystem gpio: intel-mid: switch to devm_gpiochip_add_data() gpio: 74x164: Use spi_write() helper instead of open coding ...
2016-07-24pinctrl: fix pincontrol definition for marvellAndreas Klinger1-42/+43
On Marvell mv88f6180 with pin control driver one can not use multi purpose pins 35 through 44. I'm using this controller on an embedded board and i found that the pin multiplexing is not the same as in the hardware spezification. This patch alters the pin description so that mpp pins 0 to 19 as well as 35 to 44 are usable. Pin settings i used can be found here: http://www.marvell.com/embedded-processors/kirkwood/assets/HW_88F6180_OpenSource.pdf Signed-off-by: Andreas Klinger <ak@it-klinger.de> Reviewed-by: Sebastian Hesselbarth <sebastian.hesselbarth@gmail.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2016-07-22Revert "pinctrl: amd: make it explicitly non-modular"Paul Gortmaker1-3/+20
This reverts commit b8c2b10a9bc0272a20e096852f8fbbf361749dda. This patch was in my queue at the same time that a conversion of the same driver from bool --> tristate was pending and merged. That is commit 337ea0fb1535 ("pinctrl: Turn AMD support to tristate") Normally the conflict would show up in the build coverage I do, however in this case an avoidable instance of linux/module.h in linux/gpio/driver.h (!) causes the build failure to be masked and instead the tristate gets built-in even for selected "=m". In working on removing module.h from driver.h this issue was then revealed (along with other implicit module.h assumptions in gpio, and mfd -- which will be fixed separately.)

2016-07-22pinctrl: iproc: Add NSP and Stingray GPIO supportRay Jui1-7/+111
The iProc GPIO controller is shared among multiple iProc based SoCs. In the NSP integration, the drive strength pinctrl function is disabled. In the integration of Stingray, pinctrl is handled by another block and this GPIO controller is solely used as a GPIO controller, and therefore should not be registered to the pinconf framework This patch introduces new SoC specific compatible strings "brcm,iproc-nsp-gpio" for NSP with drive strength feature disabled and "brcm,iproc-stingray-gpio" for Stingray with all PINCONF features disabled This patch is developed based on the initial work from Yendapally Reddy Dhananjaya <yendapally.reddy@broadcom.com> who attempted to disable drive strength configuration for the iProc based NSP chip. In addition, Pramod Kumar <pramod.kumar@broadcom.com> also contributed to make the support more generic across all currently supported PINCONF functions in the iProc GPIO/PINCONF driver Signed-off-by: Pramod Kumar <pramodku@broadcom.com> Signed-off-by: Ray Jui <ray.jui@broadcom.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2016-07-22pinctrl: bcm: add OF dependenciesArnd Bergmann1-0/+2
Building without CONFIG_OF gives us these warnings for the broadcom pinctrl drivers: drivers/pinctrl/bcm/pinctrl-nsp-mux.c:356:20: error: 'pinconf_generic_dt_node_to_map_group' undeclared here (not in a function) drivers/pinctrl/bcm/pinctrl-cygnus-mux.c:739:20: error: 'pinconf_generic_dt_node_to_map_group' undeclared here (not in a function) The function is only available when CONFIG_OF is set, so we should add a Kconfig dependency for both drivers.
