serdev: Introduce new bus for serial attached devices The serdev bus is designed for devices such as Bluetooth, WiFi, GPS and NFC connected to UARTs on host processors. Tradionally these have been handled with tty line disciplines, rfkill, and userspace glue such as hciattach. This approach has many drawbacks since it doesn't fit into the Linux driver model. Handling of sideband signals, power control and firmware loading are the main issues. This creates a serdev bus with controllers (i.e. host serial ports) and attached devices. Typically, these are point to point connections, but some devices have muxing protocols or a h/w mux is conceivable. Any muxing is not yet supported with the serdev bus.
