[PATCH v2] ARM: dts: sunxi: Add sid for a83t
From: kevans91
Date: Tue Dec 19 2017 - 16:05:50 EST
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.
