From c3468950ef802c659c0ac215e757163833bc563f Mon Sep 17 00:00:00 2001 From: Ping-Ke Shih Date: Tue, 6 Mar 2018 09:25:47 +0800 Subject: [PATCH] rtlwifi: btcoex: Add pre- and post- normal LPS function Normal LPS is decomposed into pre- and post- parts, so we can issue H2C with TDMA parameters in the "critical section" that dirver can't change LPS state at the moment.
