The name of I2C controller over GPIO lines node ends with '-gpio' which confuses dtschema: arch/arm/boot/dts/exynos5250-arndale.dt.yaml: soc: i2c-gpio: {'pinctrl-names': ['default'], ... 'phandle': [[65]]} is not of type 'array' From schema: lib/python3.6/site-packages/dtschema/schemas/gpio/gpio-consumer.yaml Add a '-10' (there are already 0-9 I2C controllers on the SoC) suffix to silence it. This pattern on naming i2c-gpio is already present in many other dts. No functional change.
