This is v3 of a driver for the Aspeed VUART. This version addresses feedback from Andy and Greg, and includes Rob's ack for the bindings change. The VUART is a serial device on the BMC side of the LPC bus that connects a BMC to it's host processor. We add a flag to the serial core to allow the driver to skip probing of the THRE irq behaviour, which could hang due to the host not reading bytes out of the buffer. We've been using this on systems for over a year, so it has seen a good amount of testing.
