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.

pinctrl: renesas: gpio: Use new GPIO line value setter callbacks

2025-06-13T09:25:29+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: renesas: use new pinctrl GPIO helpers

2023-11-04T09:23:19+00:00

Replace the pinctrl helpers taking the global GPIO number as argument
with the improved variants that instead take a pointer to the GPIO chip
and the controller-relative offset.

pinctrl: renesas: gpio: Use dynamic GPIO base if no function GPIOs

2022-11-17T19:34:51+00:00

Since commit 502df79b860563d7 ("gpiolib: Warn on drivers still using
static gpiobase allocation") in gpio/for-next, one or more warnings are
printed during boot on systems where the pin controller also provides
GPIO functionality:

    gpio gpiochip0: Static allocation of GPIO base is deprecated, use dynamic allocation.

Fix this for ARM-based SH/R-Mobile SoCs by:
  1. Taking into account a non-zero GPIO base in the various GPIO chip
     callbacks,
  2. Switching to dynamic allocation of the GPIO base when support for
     legacy function GPIOs is not enabled.

On SuperH SoCs using legacy function GPIOs, the GPIO bases of the GPIO
controller and the GPIO function controller must not be changed, as all
board files rely on the fixed GPIO_* and GPIO_FN_* definitions provided
by the various  header files.
