While performing PORT_RESET, upon receiving the cc disconnect signal from the underlaying tcpc device, TCPM transitions into unattached state. Consider the current type of port while determining the unattached state. In the below logs, although the port_type was set to sink, TCPM transitioned into SRC_UNATTACHED. [ 762.290654] state change SRC_READY -> PORT_RESET [ 762.324531] Setting voltage/current limit 0 mV 0 mA [ 762.327912] polarity 0 [ 762.334864] cc:=0 [ 762.347193] pending state change PORT_RESET -> PORT_RESET_WAIT_OFF @ 100 ms [ 762.347200] VBUS off [ 762.347203] CC1: 2 -> 0, CC2: 0 -> 0 [state PORT_RESET, polarity 0, disconnected] [ 762.347206] state change PORT_RESET -> SRC_UNATTACHED Signed-off-by: Badhri Jagan Sridharan <Badhri@google.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
