"WebWhy is using a platform_device for these nodes a safe assumption? Well, for the way that Linux models devices, just about all bus_types assume that its devices are children of a bus controller. For example, each i2c_client is a child of an i2c_master. Each spi_device is a child of an SPI bus. Similarly for USB, PCI, MDIO, etc. " - Gic its device id
