Subject: [PATCH 2/2] ARM: dts: rockchip: Sonoff-iHost: correct IO domain voltages
Date: Fri,  9 May 2025 16:56:57 +0800	[thread overview]
Message-ID: <20250509085657.309934-3-hao.zhang@coolkit.cn> (raw)
In-Reply-To: <20250509085657.309934-1-hao.zhang@coolkit.cn>

From: "hao.zhang" <hao.zhang@coolkit.cn>

Modify the corresponding vccio according to the schematic of
Sonoff iHost. This change aligns the device tree with the actual
hardware design and improves peripheral stability.
