This series adds an optional "sender-response-time-ms" connector property so that platforms can specify a different value. Ports that don't specify the property continue to use 60 ms, so the existing behavior is unchanged. Dependencies: Patch 2 ("usb: typec: tcpm: Allow configuring tSenderResponse via fwnode") depends on patch 1 ("dt-bindings: connector: Add time property for tSenderResponse"), as patch 1 documents the property that patch 2 parses. Signed-off-by: Amit Sunil Dhamne --- Changes in v2: - Added minimum, maximum & default constraints to the dt property.
