Subject: [PATCH 3.16 55/55] serial: 8250: Add Quark X1000 to 8250_pci.c
Date: Mon, 13 Oct 2014 04:25:09 +0200	[thread overview]
Message-ID: <20141013022446.370396304@linuxfoundation.org> (raw)
In-Reply-To: <20141013022443.729870634@linuxfoundation.org>

3.16-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bryan O'Donoghue <pure.logic@nexus-software.ie>

commit 1ede7dcca3c4fa15a518ab0473126f9c3e621e4c upstream.

Quark X1000 contains two designware derived 8250 serial ports.
Each port has a unique PCI configuration space consisting of
BAR0:UART BAR1:DMA respectively.

Unlike the standard 8250 the register width is 32 bits for RHR,IER etc
The Quark UART has a fundamental clock @ 44.2368 MHz allowing for a
bitrate of up to about 2.76 megabits per second.

This patch enables standard 8250 mode
