As per USB Type-C Spec R2.0 section 4.5.1.2 (Connecting Sources and Sinks) and section 4.5.2.2 (Connection State Machine Requirements), the typical flow for configuring a device connected to a typeC port is as below: 1. Source/sink detection 2. Orientation 3. Data role 4. VCONN 5. VBUS (USB Type-C currents) 6. The connector is now configured. We can start the PD communication that should lead into configuration of the mux if we enter a mode. But in existing code data role was set after the connector and mux are already configured. So fix this by following the spec to set the data role before the connector and mux are configured.

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.
