[PATCH 2/2] pinctrl: tegra: Add driver to configure voltage and power of io pads

2016-11-02 Thread Laxman Dewangan
NVIDIA Tegra124 and later SoCs support the multi-voltage level and low power state of some of its IO pads. The IO pads can work in the voltage of the 1.8V and 3.3V of IO power rail sources. When IO interface are not used then IO pads can be configure in low power state to reduce the power from that
