From 177055b94fb5918f32c0f5ec05891dc73e64959c Mon Sep 17 00:00:00 2001 From: Baochen Qiang Date: Mon, 10 Oct 2022 11:32:37 +0800 Subject: [PATCH] wifi: ath11k: Send PME message during wakeup from D3cold commit 3f9b09ccf7d5f23066b02881a737bee42def9d1a upstream. We are seeing system stuck on some specific platforms due to WLAN chip fails to wakeup from D3cold state. With this flag, firmware will send PME message during wakeup and this issue is gone.
