Subject: [PATCH rtw-next 14/15] wifi: rtw89: 8852b: update default value for ANA SWR
Date: Wed, 9 Sep 2026 15:00:03 +0800	[thread overview]
Message-ID: <20260909070004.35353-15-pkshih@realtek.com> (raw)
In-Reply-To: <20260909070004.35353-1-pkshih@realtek.com>

The RTL8852BE randomly card drops on certain platforms. Adjust ANA_SWR
behavior by compensation parameters to stabilize the switching regulator
output to prevent unwanted drop.
