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. *** BLURB HERE *** hao.zhang (2): ARM: dts: rockchip: Sonoff-iHost: adjust SDIO for stability ARM: dts: rockchip: Sonoff-iHost: correct IO domain voltages .../arm/boot/dts/rockchip/rv1126-sonoff-ihost.dtsi | 14 ++++++-------- 1 file changed, 6 insertions(+), 8 deletions(-) -- 2.34.1
