From: Jos Wang <joswang@xxxxxxxxxx> Add "pd2-sender-response-time-ms" and "pd3-sender-response-time-ms" DT attributes to better solve the following test items in the usb pd compliance test: TEST.PD.PROT.SRC3.2 SenderResponseTimer Timeout TEST.PD.PROT.SNK.6 SenderResponseTimer Timeout This is to enable setting of platform/board specific timer values as these timers have a range of acceptable values.
