| | | | | | | | | | | This adds VIN[0-2] pinmux support to r8a7791 SoC. VIN1 B mirror is also added along with the primary configuration since it's the only one that provides access to all 24 data bits on VIN1.

* sh-pfc: Support GPIO to IRQ mapping specified IRQ resourcesLaurent Pinchart2013-12-123-17/+68
| | | | | | | | | | | | | | | | | | On non-DT platforms IRQ controllers associated with the GPIOs have a fixed IRQ base value known at compile time. The sh-pfc driver translates GPIO number to IRQ numbers using a hardcoded table. This mechanism breaks on DT platforms, as the IRQ base values are dynamic in that case. Fix this by specifying IRQs associated with GPIOs in IRQ resources, populated automatically from the device tree. When IRQ resources are specified the driver requires one IRQ resource per GPIO able to generate an interrupt, and uses the translation table to compute the IRQ resource offset instead of the IRQ number.

* pinctrl: pinconf: remove checks on ops->pin_config_getAlexandre Belloni2013-12-121-16/+4
| | | | | | | | | | | | | | | | | | | | | ops->pin_config_get() is only used in one specific path that will only be taken for generic pinconf drivers (ops->is_generic == true) when dumping the pinconf by using debugfs. By removing the check in pinconf_check_ops(), let's stop pressuring people to write a pin_config_get() function that will never be used and so will probably never be tested. Removing the check in pinconf_pins_show() allows driver to not implement pin_config_get() but still get a dump of the pinconf in debugfs by implementing pin_config_dbg_show(). Finally, not implementing pin_config_get() now results in returning -ENOTSUPP instead of -EINVAL. While this doesn't have any real impact for now, this feels more right.

ChangeLog v1->v2: - OK so "depends on OF" did not work here let's try to simply select OF and OF_IRQ for this then?

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 ...
