- Modified src attach state to enable vbus when debug accessory is detected. - servo_v4 has two pd ports, but each port requires a different default power role. Port 0 can only ever be a SNK, but port 1 which acts is intended to be a DTS port should default to a SRC so it can be be a source debug accessory. It may also act as a sink debug accessory, but is not intended to toggle automatically but will swap roles if necessary via pd role swap messaging. - Add hook for ccd enable/disable for DTS mode BUG=chrome-os-partner:61878 BRANCH=servo TEST=Manual Verfied that can still build servo_v4 project. All changes in this CL are contingent on config option CONFIG_USB_PD_DTS being enabled.
