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-supported" is introduced and TCPM uses this property as a flag to decide whether PD is supported. If the flag is false, 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 as what it was before. If "pd-supported" is not 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 v1: - revise the patch to use dt properties Kyle Tso (2): dt-bindings: connector: Add pd-supported property usb: typec: tcpm: Support non-PD mode .../bindings/connector/usb-connector.yaml | 5 + drivers/usb/typec/tcpm/tcpm.c | 108 +++++++++++++----- 2 files changed, 84 insertions(+), 29 deletions(-) -- 2.32.0.432.gabb21c7263-goog
