Subject: [PATCH rtw-next 5/6] wifi: rtw89: pci: restore LDO setting after device resume
Date: Tue, 27 Jan 2026 16:50:35 +0800 [thread overview]
Message-ID: <20260127085036.44060-6-pkshih@realtek.com> (raw)
In-Reply-To: <20260127085036.44060-1-pkshih@realtek.com>
From: Dian-Syuan Yang <dian_syuan0116@realtek.com>
The LDO (Low Dropout Regulator) setting is missing after suspend/resume
in some platforms, and it will cause card loss. Therefore, reconfigure
this setting to avoid it.
