A representation of a group of pins (possibly just one pin) in the Tegra pin controller. Each group allows some parameter or parameters to be configured. The most common is mux function selection. Many others exist such as pull-up/down, tri-state, etc. Tegra's pin controller is complex; certain groups may only support configuring certain parameters, hence each parameter is optional, represented by a -1 "reg" value.
