From: Amit Sunil Dhamne <amitsd@google.com> TCPCI maxim driver directly writes to the charger's register space to set charger mode depending on the power role. As MAX77759 chg driver exists, this WAR is not required. Instead, use a regulator interface to source vbus when typec is in source power mode. In other power modes, this regulator will be turned off if active.
