During init, vbus_vsafe0v does not get updated till the first connect as a sink. This causes TCPM to be stuck in SRC_ATTACH_WAIT state while booting with a sink (For instance: a headset) connected. [ 1.429168] Start toggling [ 1.439907] CC1: 0 -> 0, CC2: 0 -> 0 [state TOGGLING, polarity 0, disconnected] [ 1.445242] CC1: 0 -> 0, CC2: 0 -> 0 [state TOGGLING, polarity 0, disconnected] [ 53.358528] CC1: 0 -> 0, CC2: 0 -> 2 [state TOGGLING, polarity 0, connected] [ 53.358564] state change TOGGLING -> SRC_ATTACH_WAIT [rev1 NONE_AMS] Fix this by updating vbus_vsafe0v based on vbus_present status on boot.

README
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.
