For debug purpose, it's useful to know the pins muxing to check if a pin is configured as a GPIO or as an alternate function and to get information about this alternate function configuration. For this purpose a new command pinmux is implemented.
This series adds: - Add get_pin_muxing ops to UCLASS pinctrl - Add pinmux command - Add get_function() support to stm32 gpio driver - Add get_pins_count() support to stm32 pinctrl driver - Add get_pin_name() support to stm32 pinctrl driver - Add get_pin_muxing() support to stm32 pinctrl driver Changes in v2: - Replace pinmux_show ops which displayed the complete pin-controller muxing by get_pin_muxing ops which displays the muxing of one pin - In order to make pin muxing display less SoC specific, use pinctrl_pins_count(), pinctrl_get_pin_name() and pinctrl_get_pin_muxing() methods instead of previous pinctrl_pinmux_show() method.
