Subject: [PATCH 00/18] Tegra XUSB OTG support
This patch series adds OTG support on XUSB hardware used in Tegra210 and
Tegra186 SoCs.
This patchset is composed with :
- dt bindings of XUSB Pad Controller
- dt bindings for XUSB device Driver
- Tegra PHY driver for usb-role-switch and usb-phy
- Tegra XUSB host mode driver to support OTG mode
- Tegra XUSB device mode driver to use usb-phy and multi device mode
- dts for XUSB pad controller
- dts for xudc
Tegra Pad controller driver register for role switch updates for
OTG/peripheral capable USB ports and adds usb-phy for that corresponding
USB ports.
Host and Device mode drivers gets usb-phy from USB2's phy and registers
notifier for role changes to perform corresponding role tasks.
Tests done:
- device mode support using micro-B USB cable connection between ubuntu
host and DUT on micro-B port
- host mode support by connecting pen-drive to micro USB port on DUT
using micro-B OTG cable.
- toggling between these 2 modes by hot plugging corresponding cables.
DUT: Jetson-tx1, Jetson tx2.
