Subject: [PATCH v6 2/6] Bindings: nvmem: add bindings for JZ4780 efuse
Date: Wed, 26 Feb 2020 12:15:57 +0100 [thread overview]
Message-ID: <4b243cc120ca6f9a23e217d070e7f6a42f11f8b4.1582715761.git.hns@goldelico.com> (raw)
In-Reply-To: <cover.1582715761.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.
