Subject: [PATCH] ath10k: debugfs support to get final TPC stats for 10.4
variants
Export the final Transmit Power Control (TPC) value, which is the
minimum of control power and existing TPC value to user space via
a new debugfs file "tpc_stats_final" to help with debugging.
It works with the new wmi cmd and event introduced in 10.4 firmware
branch.
WMI command ID: WMI_PDEV_GET_TPC_TABLE_CMDID
WMI event ID: WMI_PDEV_TPC_TABLE_EVENTID
