The STM32 SPI peripheral supports both SPI and I2S protocols. In the SoC device tree the node describes the peripheral as an SPI peripheral by default. This default configuration can be overwritten in board device tree to use the IP as an I2S peripheral. In this case the address-cells and size-cells properties from SoC DT SPI node should not be checked against STM32 I2S bindings. Set additionalProperties to "true" to allow these extra properties.
