2012-12-19gpio/mvebu-gpio: Make mvebu-gpio depend on OF_CONFIGGregory CLEMENT
When building without device tree support (for the mv78x00 SoCs for example), the build failed because of_irq_count is undeclared. However mvebu-gpio is not designed to build without device tree support. So make it depends on OF_CONFIG, remove the #ifdef OF_CONFIG line and the platform_device_id. Tested on RD-78x00-mASA, DB-78460-BP, DB-88F6710-BP-DDR3, DB-MV784MP-GP, Mirabox and OpenBlocks AX3.

git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6 Pull MFS update from Samuel Ortiz: "This is the MFD patch set for the 3.8 merge window. We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts.

2012-11-21gpiolib: rename pin range argumentsLinus Walleij
To be crystal clear on what the arguments mean in this funtion dealing with both GPIO and PIN ranges with confusing naming, we now have gpio_offset and pin_offset and we are on the clear that these are offsets into the specific GPIO and pin controller respectively. The GPIO chip itself will of course keep track of the base offset into the global GPIO number space.

2012-11-21gpiolib: let gpiochip_add_pin_range() specify offsetLinus Walleij
Like with commit 3c739ad0df5eb41cd7adad879eda6aa09879eb76 it is not always enough to specify all the pins of a gpio_chip from offset zero to be added to a pin map range, since the mapping from GPIO to pin controller may not be linear at all, but need to be broken into a few consecutive sub-ranges or 1-pin entries for complicated cases. The ranges may also be sparse. This alters the signature of the function to accept offsets into both the GPIO-chip local pinspace and the pin controller local pinspace.

2012-11-11gpiolib: separation of pin concernsLinus Walleij
The fact that of_gpiochip_add_pin_range() and gpiochip_add_pin_range() share too much code is fragile and will invariably mean that bugs need to be fixed in two places instead of one. So separate the concerns of gpiolib.c and gpiolib-of.c and have the latter call the former as back-end. This is necessary also when going forward with other device descriptions such as ACPI. This is done by: - Adding a return code to gpiochip_add_pin_range() so we can reliably check whether this succeeds. - Get rid of the custom of_pinctrl_add_gpio_range() from pinctrl. Instead create of_pinctrl_get() to just retrive the pin controller per se from an OF node. This composite function was just begging to be deleted, it was way to purpose-specific. - Use pinctrl_dev_get_name() to get the name of the retrieved pin controller and use that to call back into the generic gpiochip_add_pin_range(). Now the pin range is only allocated and tied to a pin controller from the core implementation in gpiolib.c. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
