patch "usb: pd: Set PD_T_SINK_WAIT_CAP to 310ms" added to usb-linus

This is a note to let you know that I've just added the patch titled

usb: pd: Set PD_T_SINK_WAIT_CAP to 310ms

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: usb: pd: Set PD_T_SINK_WAIT_CAP to 310ms

Current timer PD_T_SINK_WAIT_CAP is set to 240ms which will violate the SinkWaitCapTimer (tTypeCSinkWaitCap 310 - 620 ms) defined in the PD Spec if the port is faster enough when running the state machine. Set it to the lower bound 310ms to ensure the timeout is in Spec.
