Subject: [PATCH 1/1] ARM: dts: rockchip: Wifi improvements for Sonoff iHost
Date: Sun, 27 Apr 2025 14:50:13 +0800 [thread overview]
Message-ID: <20250427065013.99871-2-hao.zhang@coolkit.cn> (raw)
In-Reply-To: <20250427065013.99871-1-hao.zhang@coolkit.cn>
From: "hao.zhang" <hao.zhang@coolkit.cn>
After some Sonoff-iHosts have been running for a long time,
the WiFi module will run abnormally.
Adjust the pmu_io_domains and sdio properties
to solve the WiFi module operation abnormality.
