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
=>

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.
