*	gpiolib: devres: add missing headers	Alexandre Courbot	2013-10-30	1	-0/+2
\| \| \| \| \| \| \|	Add missing headers for drivers/gpiolib/devres.c. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
*	gpiolib: devres: fix devm_gpiod_get_index()	Alexandre Courbot	2013-10-23	1	-1/+1
\| \| \| \| \| \| \| \|	Fix the return value if devm_gpiod_get_index(). It was returning 0 while it should return the obtained GPIO descriptor. Signed-off-by: Alexandre Courbot <acourbot@nvidia.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
*	gpiolib: add gpiod_get() and gpiod_put() functions	Alexandre Courbot	2013-10-19	1	-0/+83
\| \| \| \| \| \| \| \| \| \| \| \|	Add gpiod_get(), gpiod_get_index() and gpiod_put() functions that provide safer management of GPIOs. These functions put the GPIO framework in line with the conventions of other frameworks in the kernel, and help ensure every GPIO is declared properly and valid while it is used.

*	gpio: devres: make comments proper	Wolfram Sang	2013-06-17	1	-7/+7
\| \| \| \| \| \| \| \|	The free-function mentioned "interrupt" instead of "GPIO". While we are here, use "GPIO" (capital letters) consistently. Signed-off-by: Wolfram Sang <wsa@the-dreams.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

Changes do touch architecture code to remove the need for separate arm/gpio.h includes in most architectures. Some new drivers are added, and a number of gpio drivers are converted to use irq_domains for gpio inputs used as interrupts. Device tree support has been amended to allow multiple gpio_chips to use the same device tree node. Remaining changes are primarily bug fixes." * tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6: (33 commits) gpio/generic: initialize basic_mmio_gpio shadow variables properly gpiolib: Remove 'const' from data argument of gpiochip_find() gpio/rc5t583: add gpio driver for RICOH PMIC RC5T583 gpiolib: quiet gpiochip_add boot message noise gpio: mpc8xxx: Prevent NULL pointer deref in demux handler gpio/lpc32xx: Add device tree support gpio: Adjust of_xlate API to support multiple GPIO chips gpiolib: Implement devm_gpio_request_one() gpio-mcp23s08: dbg_show: fix pullup configuration display Add support for TCA6424A gpio/omap: (re)fix wakeups on level-triggered GPIOs gpio/omap: fix broken context restore for non-OFF mode transitions gpio/omap: fix missing check in _runtime_suspend() gpio/omap: remove cpu_is_omapxxxx() checks from _runtime_resume() gpio/omap: remove suspend/resume callbacks gpio/omap: remove retrigger variable in gpio_irq_handler gpio/omap: remove saved_wakeup field from struct gpio_bank gpio/omap: remove suspend_wakeup field from struct gpio_bank gpio/omap: remove saved_fallingdetect, saved_risingdetect gpio/omap: remove virtual_irq_start variable ...

\| *	gpiolib: Implement devm_gpio_request_one()	Mark Brown	2012-05-19	1	-0/+29
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Allow drivers to use the modern request and configure idiom together with devres. As with plain gpio_request() and gpio_request_one() we can't implement the old school version in terms of _one() as this would force the explicit selection of a direction in gpio_request() which could break systems if we pick the wrong one. Implementing devm_gpio_request_one() in terms of devm_gpio_request() would needlessly complicate things or lead to duplication from the unmanaged version depending on how it's done.

*	GPIO: add bindings for managed devices	John Crispin	2012-01-04	1	-0/+90
	This patch adds 2 functions that allow managed devices to request GPIOs. These GPIOs will then be managed by drivers/base/devres.c. Signed-off-by: John Crispin <blogic@openwrt.org> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
