2020-08-31rtlwifi: btcoexist: Replace RT_TRACE with rtl_dbgLarry Finger
Change the misleading macro name to one that is more descriptive for btcoexist. This change exposed some conditions reported by checkpatch.pl. These are also fixed.

2018-01-24rtlwifi: btcoex: Add wifi_only series ops to control solo cardPing-Ke Shih
Originally, btcoex controls the antenna of combo card, but solo card is also needed to setup properly. The new ops are named with suffix '_wifi_only' opposited to original btc_ops, and new structures and definitions are also introduced. The wifi_only oly contains four ops that are initial variable, hw config, scan notify, and switch band notify.

2018-01-24rtlwifi: btcoex: add scan_notify within ips_notify if RFONPing-Ke Shih
Three steps of connection procedure are scan, enter/leave IPS, auth. There is no scan between leaving IPS and sending auth, but btcoex use scan as an important clue that indicates user is going to connect. So add scan notifications in ips_notify to correct btcoex's state.

This commit implement the common function to sort old features, and add more new features that are get_supported_feature, get_supported_version, get_ant_det_val, ble_scan_type, ble_scan_para, bt_dev_info, forbidden_slot_val, afh_map and etc. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2018-01-17rtlwifi: btcoex: Add power_on_setting routinePing-Ke Shih
After mac power-on sequence, wifi will start to work so notify btcoex the event to configure registers especially related to antenna. This will not only help to assign antenna but also to yield better user experience. Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-01-08rtlwifi: Improve debugging by using debugfsPing-Ke Shih
Use debugfs to dump register and btcoex status, and also write registers and h2c. We create topdir in /sys/kernel/debug/rtlwifi/, and use the MAC address as subdirectory with several entries to dump mac_reg, bb_reg, rf_reg etc. An example is /sys/kernel/debug/rtlwifi/00-11-22-33-44-55-66/mac_0 This change permits examination of device registers in a dynamic manner, a feature not available with the current debug mechanism.

2016-04-06rtlwifi: btcoexist: Implement antenna selectionLarry Finger

2015-10-14rtlwifi: rtl818x: Move drivers into new realtek directoryLarry Finger
Now that a new mac80211-based driver for Realtek devices has been submitted, it is time to reorganize the directories. Rather than having directories rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in drivers/net/wireless/realtek/. This change simplifies the directory structure, but does not result in any configuration changes that are visable to the user.
