2017-02-09	serdev: ttyport: check whether tty_init_dev() fails	Dan Carpenter
	My static checker complains that we don't have any error handling here. It's simple enough to add it.

2017-02-03	serdev: add a tty port controller driver	Rob Herring
	Add a serdev controller driver for tty ports. The controller is registered with serdev when tty ports are registered with the TTY core. As the TTY core is built-in only, this has the side effect of making serdev built-in as well.

2017-02-03	serdev: Introduce new bus for serial attached devices	Rob Herring
	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.
