Subject: [RFC v4 5/6] MIPS: DTS: JZ4780: define node for JZ4780 efuse
Date: Mon, 17 Feb 2020 17:55:29 +0100	[thread overview]
Message-ID: <b53378842303663f88ec90d6c9dc36adab1ea96c.1581958529.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1581958529.git.hns@goldelico.com>

From: PrasannaKumar Muralidharan <prasannatsmkumar@gmail.com>

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 reg range to avoid overlap.
