The device tree describes the VC04 itself with the resources required to communicate with it through a mailbox interface. However, the vchiq interface registers these devices as platform devices. This also means the specific drivers for these devices are also getting registered as platform drivers. This is not correct and a blatant abuse of platform device/driver. Replace the platform device/driver model with a standard device driver model. A custom bus_type, vchiq_bus_type, is created in the vchiq interface which matches the devices to their specific device drivers thereby, establishing driver binding. A struct vchiq_device wraps the struct device for each device being registered on the bus by the vchiq interface. Each device registered will expose a 'name' read-only device attribute in sysfs (/sys/bus/vchiq-bus/devices). New devices and drivers can be added by registering on vchiq_bus_type and adding a corresponding device name entry in the static list of devices, vchiq_devices. There is currently no way to enumerate the VCHIQ devices that are available from the firmware.
