Jos Wang 659f5d55fe usb: typec: tcpm: PSSourceOffTimer timeout in PR_Swap enters ERROR_RECOVERY ... As PD2.0 spec ("6.5.6.2 PSSourceOffTimer")，the PSSourceOffTimer is used by the Policy Engine in Dual-Role Power device that is currently acting as a Sink to timeout on a PS_RDY Message during a Power Role Swap sequence. This condition leads to a Hard Reset for USB Type-A and Type-B Plugs and Error Recovery for Type-C plugs and return to USB Default Operation. Therefore, after PSSourceOffTimer timeout, the tcpm state machine should switch from PR_SWAP_SNK_SRC_SINK_OFF to ERROR_RECOVERY. This can also solve the test items in the USB power delivery compliance test: TEST.PD.PROT.SNK.12 PR_Swap – PSSourceOffTimer Timeout [1] https://usb.org/document-library/usb-power-delivery-compliance-test-specification-0/USB_PD3_CTS_Q4_2025_OR.zip Fixes: f0690a25a1 ("staging: typec: USB Type-C Port Manager (tcpm)") Cc: stable <stable@kernel.org> Signed-off-by: Jos Wang <joswang@lenovo.com> Reviewed-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Tested-by: Amit Sunil Dhamne <amitsd@google.com> Link: https://lore.kernel.org/r/20250213134921.3798-1-joswang1221@gmail.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2025-02-14 09:26:44 +01:00
