2019-04-05drivers: gpio: clps711x: use devm_platform_ioremap_resource()Enrico Weigelt, metux IT consult1-5/+2
Use the new helper that wraps the calls to platform_get_resource() and devm_ioremap_resource() together. Signed-off-by: Enrico Weigelt, metux IT consult <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2016-06-08gpio: clps711x: Remove board supportAlexander Shiyan1-2/+6
Since board support for the CLPS711X platform was removed, remove the board support from the driver. Signed-off-by: Alexander Shiyan <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2016-06-08gpio: clps711x: Change the compatibility stringAlexander Shiyan1-1/+1
This patch changes the compatibility string to match with the smallest supported chip (EP7209). Since the DT-support for this CPU is not yet announced, this change is safe. Signed-off-by: Alexander Shiyan <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2016-02-23gpio: clps711x: Use devm_gpiochip_add_data() for gpio registrationLaxman Dewangan1-10/+1
Use devm_gpiochip_add_data() for GPIO registration and remove the need of driver callback .remove. Signed-off-by: Laxman Dewangan <[email protected]>
2016-01-05gpio: generic: factor into gpio_chip structLinus Walleij1-14/+14
The separate struct bgpio_chip has been a pain to handle, both by being confusingly similar in name to struct gpio_chip and for being contained inside a struct so that struct gpio_chip is contained in a struct contained in a struct, making several steps of dereferencing necessary. Make things simpler: include the fields directly into <linux/gpio/driver.h>, #ifdef:ed for CONFIG_GENERIC_GPIO, and get rid of the <linux/basic_mmio_gpio.h> altogether. Prefix some of the member variables with bgpio_* and add proper kerneldoc while we're at it. Modify all users to handle the change and use a struct gpio_chip directly. And while we're at it: replace all container_of() dereferencing by gpiochip_get_data() and registering the gpio_chip with gpiochip_add_data().

2014-10-20gpio: drop owner assignment from platform_driversWolfram Sang1-1/+0
A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang <[email protected]>

Linux 3.14-rc6
2014-02-06gpio: clps711x: Add missing .owner to struct gpio_chipAxel Lin1-0/+1
Add missing .owner of struct gpio_chip. This prevents the module from being removed from underneath its users. Signed-off-by: Axel Lin <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2014-02-05gpio: clps711x: Add module alias to support module auto loadingAxel Lin1-0/+1
commit 55fe14ab872a "GPIO: clps711x: Rewrite driver for using generic GPIO code" allows this driver to be built as a module. Thus add module alias to support module auto loading. Signed-off-by: Axel Lin <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2014-01-07gpio: clps711x: Use of_match_ptr()Alexander Shiyan1-2/+2
There is no reason to keep the OF data if the driver was compiled without DT support. Signed-off-by: Alexander Shiyan <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2013-10-02gpio: clps711x: Remove redundant of_match_ptrSachin Kamat1-1/+1
The data structure of_match_ptr() protects is always compiled in. Hence of_match_ptr() is not needed. Signed-off-by: Sachin Kamat <[email protected]> Signed-off-by: Linus Walleij <[email protected]>

2012-10-27GPIO: clps711x: use platform_device_unregister in gpio_clps711x_init()Wei Yongjun1-2/+1
platform_device_unregister() only calls platform_device_del() and platform_device_put(), thus use platform_device_unregister() to simplify the code. Also the documents in platform.c shows that platform_device_del and platform_device_put must _only_ be externally called in error cases. All other usage is a bug. dpatch engine is used to auto generate this patch.

2012-10-26GPIO: clps711x: Fix direction logic for PORTDAlexander Shiyan1-14/+51
PORTD have different direction logic, i.e. "0" is output and "1" is input. This patch fix this issue. Signed-off-by: Alexander Shiyan <[email protected]> Signed-off-by: Linus Walleij <[email protected]>

2012-10-15GPIO: Add support for GPIO on CLPS711X-target platformAlexander Shiyan1-0/+163
The CLPS711X CPUs provide some GPIOs for use in the system. This driver provides support for these via gpiolib. Due to platform limitations, driver does not support interrupts, only inputs and outputs.
