Subject: [PATCH 2/2] ARM: mach-imx: imx6q: Set system_rev to show soc revision
Date: Mon, 23 Nov 2020 18:08:11 +0100 [thread overview]
Message-ID: <1606151291-288303-2-git-send-email-r.karszniewicz@phytec.de> (raw)
In-Reply-To: <1606151291-288303-1-git-send-email-r.karszniewicz@phytec.de>
From: Stefan Riedmueller <s.riedmueller@phytec.de>
The system_rev value is shown in /proc/cpuinfo as Revision. Make use of
this by showing the SOC Revision there.
