From: Sowmiya Sree Elavalagan<quic_ssreeela@xxxxxxxxxxx> Host receives four Transmit Power Control(TPC) events from firmware on sending TPC request. Fixed param TLV is present as part of all event to indicate the event count and end of event. TPC config parameters along with regulatory power array comes as first event. Rates array comes as second and third event as it cannot be packed in single event. Conformance Test Limit (CTL) power array comes as the fourth event. Firmware packs different sets of array params which includes array length and type inside master TLV as different subtlvs. And the actual content of array is packed one after the other inside a separate TLV as single buffer. Parse various events and save it in local structures. Create tpc_stats file using debugfs to store these local structures. Create function to handle TPC stats read to relay the information to the user.
