From 1c413bf7f2ff372e00d2d78a8904a0ade2420f0a Mon Sep 17 00:00:00 2001 From: Julien Grall Date: Tue, 27 Aug 2013 13:13:35 +0100 Subject: drivers/char: pl011: Enable receive timeout interrupt The commit 874f76a "PL011: fix reverse logic for interrupt mask register" introduced regression on the Versatile Express. The board didn't receive correctly input. The timeout interrupt may be asserted when the FIFO is not empty, and no futher data is received over a 32-bit period.
