2022-08-31gpio: ucb1400: Use proper headerLinus Walleij1-0/+1
The UCB1400 implements a GPIO driver so it needs to include the <linux/gpio/driver.h> header, not the legacy <linux/gpio.h> header. Compile tested on pxa_defconfig. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Bartosz Golaszewski <brgl@bgdev.pl>
2022-07-19gpio: ucb1400: Remove platform setup and teardown supportUwe Kleine-König1-20/+0
There is no user of these callbacks. The motivation for this change is to stop returning an error code from the remove callback. This is a preparation for making platform remove callbacks return void. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Bartosz Golaszewski <brgl@bgdev.pl>

2016-02-23gpio: ucb1400: Use devm_gpiochip_add_data() for gpio registrationLaxman Dewangan1-2/+1
Use devm_gpiochip_add_data() for GPIO registration. Signed-off-by: Laxman Dewangan <ldewangan@nvidia.com>
2016-01-05gpio: ucb1400: use gpiochip data pointerLinus Walleij1-5/+6
This makes the driver use the data pointer added to the gpio_chip to store a pointer to the state container instead of relying on container_of(). Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2015-12-26gpio: ucb1400: Be sure to clamp return valueLinus Walleij1-1/+1
As we want gpio_chip .get() calls to be able to return negative error codes and propagate to drivers, we need to go over all drivers and make sure their return values are clamped to [0,1]. We do this by using the ret = !!(val) design pattern. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-12-04gpio/pinctrl: make gpio_chip members typed booleanLinus Walleij1-1/+1
This switches the two members of struct gpio_chip that were defined as unsigned foo:1 to bool, because that is indeed what they are. Switch all users in the gpio and pinctrl subsystems to assign these values with true/false instead of 0/1. The users outside these subsystems will survive since true/false is 1/0, atleast we set some kind of more strict typing example. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-11-25gpio: ucb1400: Add MODULE_ALIASAxel Lin1-0/+1

2012-01-02gpio: Convert GPIO drivers to module_platform_driverMark Brown1-12/+1
Where appropriate factor out some boilerplate code for platform device registration into module_platform_driver. Drivers that don't use the standard module_init initcall haven't been converted.

2011-06-06gpio: reorganize driversGrant Likely1-0/+125
Sort the gpio makefile and enforce the naming convention gpio-*.c for gpio drivers. v2: cleaned up filenames in Kconfig and comment blocks v3: fixup use of BASIC_MMIO to GENERIC_GPIO for mxc Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
