From 1db8b5efe0c2b5000e50691eea61264a615f43de Mon Sep 17 00:00:00 2001 From: Peter Crosthwaite Date: Wed, 3 Apr 2013 14:52:21 +1000 Subject: cadence_uart: Flush queued characters on reset Reset can be used to empty the rx-fifo. As the fifo full condition is used to return false from can_receive, queued rx data should be flushed on reset accordingly.
