I2C nodes should always have #address-cells and #size-cells defined, otherwise warnings will be produced in case of adding child nodes to the I2C bus in DT: Warning (avoid_default_addr_size): Relying on default #address-cells value for /soc/i2c@2530800/pca@20 Warning (avoid_default_addr_size): Relying on default #size-cells value for /soc/i2c@2530800/pca@20 Hence, ensure that all i2cX nodes have #address-cells and #size-cells properties defined.
