The WiFi tx power of RTL8723BU is extremely low after booting. So the WiFi scan gives very limited AP list and it always fails to connect to the selected AP. This module only supports 1x1 antenna and the antenna is switched to bluetooth due to some incorrect register settings. Compare with the vendor driver https://github.com/lwfinger/rtl8723bu, we realized that the 8723bu's enable_rf() does the same thing as rtw_btcoex_HAL_Initialize() in vendor driver. And it by default sets the antenna path to BTC_ANT_PATH_BT which we verified it's the cause of the wifi weak tx power. The vendor driver will set the antenna path to BTC_ANT_PATH_PTA in the consequent btcoexist mechanism, by the function halbtc8723b1ant_PsTdma. This commit hand over the antenna control to PTA(Packet Traffic Arbitration), which compares the weight of bluetooth/wifi traffic then determine whether to continue current wifi traffic or not. After PTA take control, The wifi signal will be back to normal and the bluetooth scan can also work at the same time. However, the btcoexist still needs to be handled under different circumstances. If there's a BT connection established, the wifi still fails to connect until BT disconnected. Signed-off-by: Chris Chiu <chiu@endlessm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> |

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
