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
