Subject: [PATCH 0/2] arm: dts: rockchip: Adapt to IO domain and SDIO for Sonoff iHost
Date: Fri, 9 May 2025 16:56:55 +0800 [thread overview]
Message-ID: <20250509085657.309934-1-hao.zhang@coolkit.cn> (raw)
From: "hao.zhang" <hao.zhang@coolkit.cn>
This patch series makes two corrections for the RV1126-based
Sonoff iHost board:
- Patch 1 adjusts the SDIO max-frequency to improve WiFi stability.
- Patch 2 updates the IO domain voltages to match the board schematics.
The voltage fix is based on verified schematics and helps avoid potential
hardware instability due to mismatched IO levels.
Tested on multiple units with improved long-term WiFi operation.
Tim Lunn is Cc'd as the original board support contributor.
