+Subject: [PATCH 1/2] PLDM: add StateReading interface
+
+Simple interface to hold PLDM state sensor reading.
+PLDM state sensor reading may contain multiple (1 ~ 8) state set ID, so
+here we use an array of struct [ StateSetID, sensorOperationalState,
+presentState, previousState, eventState ].
+
+Patch Tracking Bug: b/335329945
+Upstream info / review: N/A
+Upstream-Status: Pending
+Justification: Needed for PLDM state sensor
