Subject: [PATCH v4 2/3] can: sja1000: add documentation for Technologic Systems version
Date: Wed, 13 Jan 2016 12:46:05 +0100	[thread overview]
Message-ID: <1452685566-27431-3-git-send-email-mkl@pengutronix.de> (raw)
In-Reply-To: <1452685566-27431-1-git-send-email-mkl@pengutronix.de>

From: Damien Riegel <damien.riegel@savoirfairelinux.com>

This commit adds documentation for the Technologic Systems version of
SJA1000. The difference with the NXP version is in the way the registers
are accessed.
