[PATCH v2 0/3] Add AHT20 sensor bindings and fix driver initialization
From: Hao Yu
Date: Sun Feb 22 2026 - 12:03:50 EST
This patch series adds device tree binding documentation for Aosong
AHT10/AHT20 series sensors, fixes the initialization command sequence
for AHT20, and adds Device Tree support to the driver.
The AHT20 sensor was tested on a rk3566_lckfb board with the I2C-2 port.
Temperature and humidity readings are now accurate after fixing the
initialization command.
Changes in v2:
- Split the driver patch into two separate commits:
- Patch 2/3: A fix for the initialization bug (includes Fixes tag).
- Patch 3/3: A feature patch for adding Device Tree support.
- Improved the commit message for the initialization fix with a detailed
explanation as requested by Guenter Roeck.
- Fixed indentation in aht10.c (ensured tab usage after macro definition).
