Subject: [PATCH v2] ARM: dts: sunxi: Add sid for a83t
Date: Tue, 19 Dec 2017 15:05:23 -0600	[thread overview]
Message-ID: <20171219210523.10428-1-kevans91@ksu.edu> (raw)

Allwinner a83t has a 1 KB sid block with efuse for security rootkey and
thermal calibration data, add node to describe it.

a83t-sid is not currently supported by nvmem/sunxi-sid, but it is
supported in an external driver for FreeBSD.
