2018-01-08rtlwifi: btcoex: Use seq_file to dump btcoex statusPing-Ke Shih
We use seq_file to replace RT_TRACE to dump status, then we can use 'cat' to access btcoex's status through debugfs. (i.e. /sys/kernel/debug/rtlwifi/00-11-22-33-44-55-66/btcoex) Other related changes are 1. implement btc_disp_dbg_msg() to access btcoex's common status. 2. remove obsolete field bt_exist Signed-off-by: Ping-Ke Shih <pkshih@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2017-06-13rtlwifi: btcoex: add settings before the hardware is readyYan-Hsuan Chuang
When the hardware is turned on and in the initialization stage, the PTA circuit is unstable. Hence we need to force some hardware settings to make sure the PTA circuit work correctly, otherwise it may affect the user's experience.

2017-06-13rtlwifi: btcoex: settings before firmware is downloadedYan-Hsuan Chuang
The btcoex is sometimes unstable because there are some unexpected behaviors before the firmware has been downloaded successfully. Therefore we force the antenna path settings to avoid this, then let the firmware control the btcoexistence when the firmware is ready.

2017-05-18rtlwifi: btcoex: Remove 23b 2ant configuration parameterLarry Finger
In file halbtc8723b2ant.c, there are directives that depend on an undocumented configuration parameter BT_AUTO_REPORT_ONLY_8723B_2ANT that cannot be set from Kconfig. This parameter is replaced by a boolean in the main structure used by all routines. It still cannot be changed dynamically, but it is easier to document. Routines halbtc8723b2ant_set_bt_auto_report(), and btc8723b2ant_bt_auto_report() are restored.

For 2-antenna combo card, the signal of the neighbor antenna could be over noise level and cause be severe interference. So we monitor the rssi and turn off one of the antennas when the other is transmitting and the rssi level is beyond a threshold.

If bt is queing, we need to set the packet priority properly. Originally we only consider if wifi was connected or not, but now we also consider if bt is under abnormal scan or wifi is scanning, roaming or linking, and set the coex table.

2017-04-13rtlwifi: btcoex: 23b 2ant: check PS state before setting tdma durationYan-Hsuan Chuang
For time division multiple access, the wifi and bt take turns to transmit, but we need to let AP know that wifi is under standby mode by sending null data to "pretend" entering power saving state using lps rpwm. But, the fw does not know if it is the actual power saving mode or just a fake one to cheat to the AP. Hence, before fw setting the tdma duration, the fw needs the driver to check the power saving state first.

The bt can specify a power level to decrease. Rather than decreasing by a fixed value (usually 2), this change makes the driver fit to the environment more quickly.

2017-04-05rtlwifi: btcoex: 23b 2ant: adjust wifi duration for bt a2dpYan-Hsuan Chuang
The larger the bt a2dp bit pool is, the more time bt needs to receive them. If we do not adjust the wifi duration, the voice quality will be low. Hence we reduce the time that wifi holds, to improve the a2dp service.

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.
