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. V4: - Added ACKed-by details for PHY driver. - Used BIT macro instead of (1 << index) usage as suggested by Chunfeng Yun. V3: - Added ACKed-by details for PHY driver and DT changes. - Functions and its arguments are aligned. - Tabs are used for alignment of MACRO's - For vbus_draw USDC callback, usb_phy set_power error is propogated. - Fixed various comments given by thierry. V2: - Added ACKed-by details for DT patches. - All patches rebased.
