This patch series adds charger detect support on XUSB hardware used in Tegra210 and Tegra186 SoCs. This patchset is composed with : - dt bindings of XUSB Pad Controller - Tegra XUSB device mode driver to add vbus_draw support - Tegra PHY driver for charger detect support Tests done: - Connect USB cable from ubuntu host to micro-B port of DUT to detect SDP_TYPE charger - Connect USB cable from external powered USB hub(which inturn connects to ubuntu host) to micro-B port of DUT to detect CDP_TYPE charger. - Connect USB cable from USB charger to micro-B port of DUT to detect DCP_TYPE charger. DUT: Jetson-tx1, Jetson tx2.
