From a9aaf1ff88a8cb99a1335c9eb76de637f0cf8c10 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Tue, 13 Aug 2024 21:07:50 +0200 Subject: [PATCH] power: sequencing: request the WLAN enable GPIO as-is If the WCN module is powered up before linux boots and the ath11k driver probes at the same time as the power sequencing driver, we may end up driving the wlan-enable GPIO low in the latter, breaking the start-up of the WLAN module. Request the wlan-enable GPIO as-is so that if the WLAN module is already starting/started, we leave it alone.
