Subject: [PATCH 3/4] ARM: shmobile: Document DT bindings for Product Register
Date: Thu, 17 Nov 2016 15:04:36 +0100 [thread overview]
Message-ID: <9eb11f7d133c50c21544e1f529815aa582dcccd4.1479389981.git.horms+renesas@verge.net.au> (raw)
In-Reply-To: <cover.1479389981.git.horms+renesas@verge.net.au>
From: Geert Uytterhoeven <geert+renesas@glider.be>
Add device tree binding documentation for the Product Register (PRR),
which provides product and revision information on most Renesas ARM
SoCs.
