    pinctrl bindings used by client devices.
    
    SPEAr's pinmux nodes act as a container for an arbitrary number of subnodes. Each
    of these subnodes represents muxing for a pin, a group, or a list of pins or
    groups.
    
    The name of each subnode is not important; all subnodes should be enumerated
    and processed purely based on their content.
    
    Required subnode-properties:
    - st,pins : An array of strings. Each string contains the name of a pin or
      group.
    - st,function: A string containing the name of the function to mux to the pin or
      group. See the SPEAr's TRM to determine which are valid for each pin or group.
    
      Valid values for group and function names can be found from looking at the
      group and function arrays in driver files:
      drivers/pinctrl/spear/pinctrl-spear3*0.c
    
    Valid values for group names are:
