Subject: [PATCH 07/23] m68knommu: make 5307 UART platform addressing consistent
Date: Thu, 23 Feb 2012 14:34:39 +1000	[thread overview]
Message-ID: <1329971695-2203-8-git-send-email-gerg@snapgear.com> (raw)
In-Reply-To: <1329971695-2203-1-git-send-email-gerg@snapgear.com>

From: Greg Ungerer <gerg@uclinux.org>

If we make all UART addressing consistent across all ColdFire family members
then we will be able to remove the duplicated plaform data and use a single
setup for all.

So modify the ColdFire 5307 UART addressing so that:

. UARTs are numbered from 0 up
. base addresses are absolute (not relative to MBAR peripheral register)
. use a common name for IRQs used
