Subject: [PATCH v2 5/5] ARM: dts: TS-4800: add basic device tree
Date: Thu, 29 Oct 2015 16:27:30 -0400 [thread overview]
Message-ID: <1446150450-22093-6-git-send-email-damien.riegel@savoirfairelinux.com> (raw)
In-Reply-To: <1446150450-22093-1-git-send-email-damien.riegel@savoirfairelinux.com>
This device tree adds support for TS-4800 by Technologic Systems. This
board is based on MX51-babbage, but there are some subtle differences in
the pins used, and there is an additional FPGA that is memory-mapped.
More details here:
