[PATCH v1 0/2] usb: typec: handle tcpc vconn oc fault by triggering tcpm error recovery
Posted by RD Babiera 2 years ago
When a Vconn swap results in a Vconn over current fault, typec port
interoperability is affected and cannot be recovered unless the connection
is reset and restablished.

The tcpm currently does not have an export symbol to set the port to the
error recovery state in the event of tcpc faults. This patch set adds
tcpm_port_error_recovery for tcpci drivers to use when a fault should
result in a connection reset. Vconn over current fault handling is added
to the maxim tcpci driver.

RD Babiera (2):
  usb: typec: tcpm: add tcpm_port_error_recovery symbol
  usb: typec: tcpci: add vconn over current fault handling to maxim_core
