Subject: [PATCH v3] ARM: dts: sunxi: Add sid for a83t
Date: Thu, 19 Apr 2018 09:11:03 -0500	[thread overview]
Message-ID: <20180419141103.38196-1-kevans@FreeBSD.org> (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.
