This patch adds support for STUSB1600 USB Type-C port controller, used on I2C4 on stm32mp15xx-dkx. The default configuration on this board, on Type-C connector, is: - Dual Power Role (DRP), so set power-role to "dual"; - Vbus limited to 500mA, so set typec-power-opmode to "default" (it means 500mA in USB 2.0). typec-power-opmode is used to reconfigure the STUSB1600 advertising of current capability when its NVM is not in line with the board layout. On stm32mp15xx-dkx, Vbus power source of STUSB1600 is 5V_VIN. So power operation mode depends on the power supply used. To avoid any power issues, it is better to limit Vbus to 500mA on this board. ALERT# is the interrupt pin of STUSB1600. It needs an external pull-up, and signal is active low. USB OTG controller ID and Vbus signals are not connected on stm32mp15xx-dkx boards, so disconnection are not detected. Without DWC2 usb-role-switch: - if you unplug the USB cable from the Type-C port, you have to manually disconnect the USB gadget: echo disconnect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect - Then you can plug the USB cable again in the Type-C port, and manually reconnect the USB gadget: echo connect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect With DWC2 usb-role-switch, USB gadget is dynamically disconnected or connected.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
