From 41e043498978ad3c8d5a70613f41195faf09663f Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Mon, 9 Oct 2017 15:26:39 +0200 Subject: dt-bindings: nvmem: Describe the Amlogic Meson6/Meson8/Meson8b efuse Amlogic Meson6, Meson8 and Meson8b SoCs have an efuse which contains calibration data from the factory (for the internal temperature sensor and some CVBS connector settings). Some manufacturers also store the MAC address or serial number in the efuse. This documents the devicetree bindings for the efuse on these SoCs.
