From 60f44100eee785b5bdb475d05760ff15707fd1b7 Mon Sep 17 00:00:00 2001 From: Yan-Hsuan Chuang Date: Mon, 5 Jun 2017 10:29:55 -0500 Subject: [PATCH] rtlwifi: btcoex: add settings before the hardware is ready 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.
