Subject: [PATCH v2 08/29] ARM: davinci: dm644-evm: use nvmem lookup for mac address
Date:   Fri, 10 Aug 2018 10:05:05 +0200
Message-Id: <20180810080526.27207-9-brgl@bgdev.pl>
In-Reply-To: <20180810080526.27207-1-brgl@bgdev.pl>
References: <20180810080526.27207-1-brgl@bgdev.pl>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

We now support nvmem lookups for machine code. Add a lookup for
mac-address.
