[v2] arm: dts: rockchip: Adapt to IO domain and SDIO for Sonoff iHost

[PATCH v2 0/2] arm: dts: rockchip: Adapt to IO domain and SDIO for Sonoff iHost

Posted by Hao Zhang 7 months, 1 week ago

Changes since v1:
- Use full name 'Hao Zhang' instead of login in From and Signed-off-by

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.
