+pinmux command +==============
+Synopsis +--------
+::
- pinmux list
- pinmux dev [pincontroller-name]
- pinmux status [-a | pin-name]
+Description +-----------
+The pinmux command is used to show the pin-controller muxing.
+The 'pinmux list' command diplays the available pin-controller.
+The 'pinmux dev' command selects the pin-controller for next commands.
- pincontroller-name
name of the pin-controller to select
+The 'pinmux status' command displays the pin muxing information.
- -a
display pin muxing of all pin-controllers.
- pin-name
name of the pin to display
+Example +-------
+::
- => pinmux list
- | Device | Driver | Parent
- | pinctrl-gpio | sandbox_pinctrl_gpio | root_driver
- | pinctrl | sandbox_pinctrl | root_driver
- =>
- => pinmux dev pinctrl
- dev: pinctrl
- =>
- => pinmux status
- P0 : UART TX.
- P1 : UART RX.
- P2 : I2S SCK.
- P3 : I2S SD.
- P4 : I2S WS.
- P5 : GPIO0 bias-pull-up input-disable.
- P6 : GPIO1 drive-open-drain.
- P7 : GPIO2 bias-pull-down input-enable.
- P8 : GPIO3 bias-disable.
- =>
- => pinmux status P0
- P0 : UART TX.

- => pinmux status -a
- pinctrl-gpio:
- a0 : gpio input .
- a1 : gpio input .
- a2 : gpio input .
- a3 : gpio input .
- a4 : gpio input .
- a5 : gpio output .
- a6 : gpio output .
- a7 : gpio input .
- a8 : gpio input .

- pinctrl:
- P0 : UART TX.
- P1 : UART RX.
- P2 : I2S SCK.
- P3 : I2S SD.
- P4 : I2S WS.
- P5 : GPIO0 bias-pull-up input-disable.
- P6 : GPIO1 drive-open-drain.
- P7 : GPIO2 bias-pull-down input-enable.
- P8 : GPIO3 bias-disable.
+Configuration +-------------
+The pinmux command is only available if CONFIG_CMD_PINMUX=y.
+Return value +------------
+The return value $? is set to 0 (true) if the command succeded and to 1 (false) +otherwise.
