The upcoming chip 8851B has two variety hardware modules; one is single one antenna module, the other is two antenna module that needs this mechanism to have benefit. To help verify and debug this feature, patches 3/7 and 4/7 are to add the debug information. The last two patches are to add RSSI and EVM based antenna diversity respectively. v2: - correct wording of subject of patch 1/7 and 5/7 - no change of patch content Eric Huang (3): wifi: rtw89: initialize antenna for antenna diversity wifi: rtw89: add RSSI based antenna diversity wifi: rtw89: add EVM for antenna diversity Ping-Ke Shih (4): wifi: rtw89: use struct rtw89_phy_sts_ie0 instead of macro to access PHY IE0 status wifi: rtw89: set capability of TX antenna diversity wifi: rtw89: add RSSI statistics for the case of antenna diversity to debugfs wifi: rtw89: add EVM and SNR statistics to debugfs drivers/net/wireless/realtek/rtw89/core.c | 75 ++++- drivers/net/wireless/realtek/rtw89/core.h | 34 +++ drivers/net/wireless/realtek/rtw89/debug.c | 24 +- drivers/net/wireless/realtek/rtw89/mac.c | 9 + drivers/net/wireless/realtek/rtw89/mac80211.c | 7 +- drivers/net/wireless/realtek/rtw89/phy.c | 261 ++++++++++++++++++ drivers/net/wireless/realtek/rtw89/phy.h | 12 + drivers/net/wireless/realtek/rtw89/reg.h | 21 +- drivers/net/wireless/realtek/rtw89/txrx.h | 19 +- 9 files changed, 437 insertions(+), 25 deletions(-)
