So it is not possible to use the HID to determine whether it is I2C or SPI. The driver must check the node to see if it contains I2cSerialBus or SpiSerialBus entries. For backwards-compatibility with the existing nodes I2C is checked first and if such entries are found ONLY I2C devices are created. Since some existing nodes that were already handled by this driver could also contain unrelated SpiSerialBus nodes that were previously ignored, and this preserves that behavior. If there is ever a need to handle a node where both I2C and SPI devices must be instantiated this can be added in future.
