* gpio: Explicitly include correct DT includesRob Herring2023-07-191-1/+1
| | | | | | | | | | | | | | | | The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

* gpio: ge: Remove duplicate assignment of of_gpio_n_cellsAndy Shevchenko2023-01-301-1/+0
| | | | | | | | The of_gpio_n_cells default is 2 when ->of_xlate() callback is not defined. No need to assign it explicitly in the driver. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Bartosz Golaszewski <[email protected]>
* gpio: Get rid of duplicate of_node assignment in the driversAndy Shevchenko2021-12-171-1/+0
| | | | | | | | | | | | | | GPIO library does copy the of_node from the parent device of the GPIO chip, there is no need to repeat this in the individual drivers. Remove these assignment all at once. For the details one may look into the of_gpio_dev_init() implementation. While at it, remove duplicate parent device assignment where it is the case.

* gpio: generic: factor into gpio_chip structLinus Walleij2016-01-051-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

The GE GPIO driver provides basic support (set direction, read/write state) for the GPIO provided on some GE single board computers. This patch moves the driver from the 86xx specific platform directrory to the GPIO subsystem so that it can be used on non-86xx boards.
