cover-letter is the same as that in v4 The reason for this patch is to let the device/system policy decide whether PD is going to be supported using devicetree properties. A new dt property "pd-unsupported" is introduced and TCPM uses this property as a flag to decide whether PD is supported. If the flag is false (the dt property is not present), the RX functionality of the low-level driver will not be enabled. The power negotiation related states will be skipped as well. If the flag is true, everything is a what it was before. If "pd-unsupported" is present, and the port is SRC or DRP, another existing dt property "typec-power-opmode" needs to be specified to indicate which Rp value should be used when the port is SRC. changes since v4: dt-bindings: connector: Add pd-unsupported property - Corrected the subject usb: typec: tcpm: Support non-PD mode - Added Reviewed-by Kyle Tso (2): dt-bindings: connector: Add pd-unsupported property usb: typec: tcpm: Support non-PD mode .../bindings/connector/usb-connector.yaml | 4 + drivers/usb/typec/tcpm/tcpm.c | 87 +++++++++++++++---- 2 files changed, 72 insertions(+), 19 deletions(-) -- 2.32.0.554.ge1b32706d8-goog
