I/O pins on Tegra SoCs are grouped into so-called I/O pads. Each such pad can be used to control the common voltage signal level and power state of the pins in the given pad. I/O pads can be powered down even if the system is active, which can save power from that I/O interface. For SoC generations prior to Tegra124 the I/O pad voltage is automatically detected and hence the system software doesn't need to configure it. However, starting with Tegra210 the detection logic has been removed, so explicit control of the I/O pad voltage by system software is required.
