Badhri Jagan Sridharan 740c938147 usb: typec: tcpm: Ignore CC and vbus changes in PORT_RESET change
commit 901789745a053286e0ced37960d44fa60267b940 upstream.

After PORT_RESET, the port is set to the appropriate
default_state. Ignore processing CC changes here as this
could cause the port to be switched into sink states
by default.

echo source > /sys/class/typec/port0/port_type

Before:
[  154.528547] pending state change PORT_RESET -> PORT_RESET_WAIT_OFF @ 100 ms
[  154.528560] CC1: 0 -> 0, CC2: 3 -> 0 [state PORT_RESET, polarity 0, disconnected]
[  154.528564] state change PORT_RESET -> SNK_UNATTACHED

After:
[  151.068814] pending state change PORT_RESET -> PORT_RESET_WAIT_OFF @ 100 ms [rev3 NONE_AMS]
[  151.072440] CC1: 3 -> 0, CC2: 0 -> 0 [state PORT_RESET, polarity 0, disconnected]
[  151.172117] state change PORT_RESET -> PORT_RESET_WAIT_OFF [delayed 100 ms]
[  151.172136] pending state change PORT_RESET_WAIT_OFF -> SRC_UNATTACHED @ 870 ms [rev3 NONE_AMS]
[  152.060106] state change PORT_RESET_WAIT_OFF -> SRC_UNATTACHED [delayed 870 ms]
[  152.060118] Start toggling

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.
