Subject: [PATCH 1/2] ARM: dts: imx: Mark IIM as syscon on i.MX51/i.MX53
Date: Wed, 27 Jan 2021 18:40:23 +0100 [thread overview]
Message-ID: <20210127174024.170408-2-sebastian.reichel@collabora.com> (raw)
In-Reply-To: <20210127174024.170408-1-sebastian.reichel@collabora.com>
IIM contains system fuses with information like SoC unique ID
(serial) on i.MX51 and i.MX53. Add "syscon" compatible allowing
simple access.
