Subject: [PATCH 2/3] MIPS: qemu-malta: debug_ll: fix serial port speed
Date: Fri, 13 Feb 2015 08:53:13 +0300	[thread overview]
Message-ID: <1423806794-23881-3-git-send-email-antonynpavlov@gmail.com> (raw)
In-Reply-To: <1423806794-23881-1-git-send-email-antonynpavlov@gmail.com>

qemu-malta.dts uses clock-frequency = <1843200>,
but debug_ll.h for Malta uses another value.

This patch fixes this inconsistency.
