From 190607f2d59e174bcf8415efb1bb390737f8d428 Mon Sep 17 00:00:00 2001 From: PrasannaKumar Muralidharan Date: Fri, 28 Feb 2020 17:00:52 +0100 Subject: [PATCH] MIPS: DTS: JZ4780: define node for JZ4780 efuse This patch brings support for the JZ4780 efuse. Currently it only exposes a read only access to the entire 8K bits efuse memory and the ethernet mac address for the davicom dm9000 chip on the CI20 board. It also changes the nemc ranges definition to give the driver access to the efuse registers, which are in the middle of the nemc reg range.
