Subject: [PATCH v4 0/2] drivers: serial: Aspeed VUART driver
Date: Tue, 2 May 2017 17:15:41 +0930 [thread overview]
Message-ID: <20170502074543.1380-1-joel@jms.id.au> (raw)
This is v4 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.
Cheers,
Joel
