pinctrl: check ops->pin_config_set in pinconf_set_config()

2017-08-14T13:01:59+00:00

pinconf_set_config() is called by pinctrl_gpio_set_config().
If a GPIO driver is backed by a pinctrl driver and it does not
support .pin_config_set() hook, it causes NULL pointer dereference.

pinctrl: Replace two seq_printf() calls by seq_puts() in pinconf_show_map()

2017-05-22T08:39:24+00:00

Strings which did not contain data format specifications should be put
into a sequence. Thus use the corresponding function "seq_puts".

This issue was detected by using the Coccinelle software.

A single character (line break) should be put into a sequence.
Thus use the corresponding function "seq_putc".

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.
