Subject: [PATCH 2/9] arm64: dts: r8a7795: Add CAN FD support
Date: Thu, 30 Jun 2016 16:15:00 +0200	[thread overview]
Message-ID: <341eb484b14a16fd32086e7dd82a9f7fdea2d040.1467291676.git.horms+renesas@verge.net.au> (raw)
In-Reply-To: <cover.1467291676.git.horms+renesas@verge.net.au>

From: Ramesh Shanmugasundaram <ramesh.shanmugasundaram@bp.renesas.com>

Adds CAN FD controller node for r8a7795.

Note: CAN FD controller register base address specified in R-Car Gen3
Hardware User Manual v0.5E is incorrect. The correct address is:

CAN FD - 0xe66c0000
