From: Maharaja Kennadyrajan <c_mkenna@xxxxxxxxxxxxxxxx>
The Transmit Power Control (TPC) dump will show the power control values for
each rate which makes it easier to debug calibration problems.
Example usage:
# cat /sys/kernel/debug/ieee80211/phy0/ath10k/tpc_stats
TPC config for channel 5180 mode 10
CTL = 0x10 Reg. Domain = 58
Antenna Gain = 1 Reg. Max Antenna Gain = 0
Power Limit = 34 Reg. Max Power = 34
Num tx chains = 3 Num supported rates = 155
**********CDD POWER TABLE*******
No. Preamble Rate_code tpc_valu1 tpc_value2 tpc_value3
0 CCK 0x40 0 0 0
1 CCk 0x41 0 0 0
[...]
154 HTCUP 0x 0 24 0 0
**********STBC POWER TABLE******
No. Preamble Rate_code tpc_valu1 tpc_value2 tpc_value3
0 CCK 0x40 0 0 0
[...]
154 HTCUP 0x 0 24 24 0
**********TXBF POWER TABLE******
is used to dump the tx power control stats.
