treewide: rename pinctrl_gpio_set_config_new()

2023-11-04T09:23:22+00:00

Now that pinctrl_gpio_set_config() is no longer used, let's drop the
'_new' suffix from its improved variant.

Now that pinctrl_gpio_free()() is no longer used, let's drop the '_new'
suffix from its improved variant.

gpiolib: generic: use new pinctrl GPIO helpers

2023-11-04T09:23:18+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.

gpiolib: remove gpiochip_find()

2023-11-04T09:22:52+00:00

With all users of gpiochip_find() converted to using gpio_device_find(),
we can now remove this function from the kernel.

gpiolib: provide gpio_device_get_base()

2023-10-13T07:05:57+00:00

Let's start adding getters for the opaque struct gpio_device. Start with
a function allowing to retrieve the base GPIO number.

gpiolib: provide gpiod_to_gpio_device()

2023-10-13T06:50:04+00:00

Accessing struct gpio_chip backing a GPIO device is only allowed for the
actual providers of that chip.

Similarly to how we introduced gpio_device_find() in order to replace
the abused gpiochip_find(), let's introduce a counterpart to
gpiod_to_chip() that returns a reference to the GPIO device owning the
descriptor. This is done in order to later remove gpiod_to_chip()
entirely.

gpiolib: provide gpio_device_to_device()

2023-10-13T06:50:01+00:00

There are users in the kernel who need to retrieve the address of the
struct device backing the GPIO device. Currently they needlessly poke in
the internals of GPIOLIB. Add a dedicated getter function.

gpiolib: provide gpio_device_find_by_fwnode()

2023-10-12T08:36:39+00:00

One of the ways of looking up GPIO devices is using their fwnode.
Provide a helper for that to avoid every user implementing their
own matching function.

gpiolib: replace find_chip_by_name() with gpio_device_find_by_label()

2023-10-04T11:35:49+00:00

Remove all remaining uses of find_chip_by_name() (and subsequently:
gpiochip_find()) from gpiolib.c and use the new
gpio_device_find_by_label() instead.
