Subject: [PATCH 0/2] drivers: serial: Aspeed VUART driver

This is a driver for the Aspeed VUART. 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.

Cheers,

Joel
