From 94907e8d135b61011d157097c92c9f28983d96ea Mon Sep 17 00:00:00 2001 From: Ping-Ke Shih Date: Mon, 29 Jan 2018 11:26:41 +0800 Subject: [PATCH] rtlwifi: btcoex: Add 8822be btcoex supported files for wifi only The wifi only btcoex is used to solo card (without BT), and it is also useful to exclude the interference with BT to make debug easier. There are only four ops for wifi only btcoex to initialze antenna and switch the settings while band is changed.
