From 11a64888c79bb0bb62f575e5fe158af434155566 Mon Sep 17 00:00:00 2001 From: Yan-Hsuan Chuang Date: Wed, 18 Mar 2020 17:52:24 +0800 Subject: [PATCH] rtw88: 8822c: config RF table path B before path A After MAC switched power, the hardware's RF registers will have its default value, but the default value for path B is incorrect. So, load RF path B first, to decrease the period between MAC on and RF path B config. By test, if we load path A first, then there's ~300ms that the path B is incorrect, it could lead to BT coex's A2DP glitch. But if we configure path B first, there will only have ~3ms, significantly lower possibility to have A2DP sound glitch.
