treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

The conversion of all GPIO drivers to using the .set_rv() and .set_multiple_rv() callbacks from struct gpio_chip (which - unlike their predecessors - return an integer and allow the controller drivers to indicate failures to users) is now complete and the legacy ones have been removed. Rename the new callbacks back to their original names in one sweeping change. Signed-off-by: Bartosz Golaszewski

pinctrl: bcm: nsp-gpio: use new GPIO line value setter callbacks

2025-05-09T08:05:52+00:00

struct gpio_chip now has callbacks for setting line values that return an integer, allowing to indicate failures. Convert the driver to using them.

pinctrl: Use str_enable_disable-like helpers

2025-01-15T11:52:26+00:00

Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

pinctrl: nsp-gpio: Silence probe deferral messages

2023-08-10T08:41:20+00:00

We can have gpiochip_add_data() return -EPROBE_DEFER which will make us produce the "unable to add GPIO chip" message which is confusing. Use dev_err_probe() to silence probe deferral messages.

pinctrl: Explicitly include correct DT includes

2023-07-20T19:41:24+00:00

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.

pinctrl: Get rid of duplicate of_node assignment in the drivers

2021-12-16T03:18:30+00:00

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.

pinctrl: nsp: Set irq handler based on trig type

2020-07-11T21:09:12+00:00

Rather than always using handle_simple_irq() as the gpio_irq_chip handler, set a more appropriate handler based on the IRQ trigger type requested. This is important for level triggered interrupts which need to be masked during handling. Also, fix the interrupt acknowledge so that it clears only one interrupt instead of all interrupts which are currently active. Finally there is no need to clear the interrupt during the interrupt handler, since the edge-triggered handler will do that for us.
