pinctrl: Clean up headers

2022-10-24T14:06:48+00:00

There is a few things done: - include only the headers we are direct user of - when pointer is in use, provide a forward declaration - add missing headers - group generic headers and subsystem headers - sort each group alphabetically While at it, fix some awkward indentations.

pinctrl: core: Add pinctrl_select_default_state() and export it

2019-12-13T12:51:06+00:00

It has turned out that some mmc host drivers, but perhaps also others drivers, needs to reset the pinctrl into the default state (PINCTRL_STATE_DEFAULT). However, they can't use the existing pinctrl_pm_select_default_state(), as that requires CONFIG_PM to be set. This leads to open coding, as they need to look up the default state themselves and then select it. To avoid the open coding, let's introduce pinctrl_select_default_state() and make it available independently of CONFIG_PM. As a matter of fact, this makes it more consistent with the behaviour of the driver core, as it already tries to looks up the default state during probe. Going forward, users of pinctrl_pm_select_default_state() are encouraged to move to pinctrl_select_default_state(), so the old API can be removed.

pinctrl/gpio: Take MUX usage into account

2019-08-23T09:09:41+00:00

The user space like gpioinfo only see the GPIO usage but not the MUX usage (e.g. I2C or SPI usage) of a pin. As a user we want to know which pin is free/safe to use. So take the MUX usage of strict pinmux controllers into account to get a more realistic view for ioctl GPIO_GET_LINEINFO_IOCTL.

pinctrl/gpio: Unify namespace for cross-calls

2017-09-22T09:02:10+00:00

The pinctrl_request_gpio() and pinctrl_free_gpio() break the nice namespacing in the other cross-calls like pinctrl_gpio_foo(). Just rename them and all references so we have one namespace with all cross-calls under pinctrl_gpio_*(). Signed-off-by: Linus Walleij

pinctrl: Allow configuration of pins from gpiolib based drivers

2017-01-26T14:23:01+00:00

When a GPIO driver is backed by a pinctrl driver the GPIO driver sometimes needs to call the pinctrl driver to configure certain things, like whether the pin is used as input or output. In addition to this there are other configurations applicable to GPIOs such as setting debounce time of the GPIO. To support this we introduce a new function pinctrl_gpio_set_config() that can be used by gpiolib based driver to pass configuration requests to the backing pinctrl driver.

pinctrl: rip out the direct pinconf API

2013-06-25T10:54:56+00:00

From the inception ot the pin config API there has been the possibility to get a handle at a pin directly and configure its electrical characteristics. For this reason we had: int pin_config_get(const char *dev_name, const char *name, unsigned long *config); int pin_config_set(const char *dev_name, const char *name, unsigned long config); int pin_config_group_get(const char *dev_name, const char *pin_group, unsigned long *config); int pin_config_group_set(const char *dev_name, const char *pin_group, unsigned long config); After the introduction of the pin control states that will control pins associated with devices, and its subsequent introduction to the device core, as well as the introduction of pin control hogs that can set up states on boot and optionally also at sleep, this direct pin control API is a thing of the past. As could be expected, it has zero in-kernel users. Let's delete this API and make our world simpler.
