Each of these subnodes represents some desired configuration for a 20 pin, a group, or a list of pins or groups. This configuration can include the 21 mux function to select on those pin(s)/group(s), and various pin configuration 22 parameters, such as pull-up, slew rate, etc. 23 24 Each configuration node can consist of multiple nodes describing the pinmux and 25 pinconf options. Those nodes can be pinmux nodes or pinconf nodes. 26 27 The name of each subnode is not important; all subnodes should be enumerated 28 and processed purely based on their content. 29 30properties: 31
