Subject: [PATCH 10/28] ARM: davinci: da830-evm: use nvmem lookup for mac address
Date:   Wed,  8 Aug 2018 17:31:32 +0200
Message-Id: <20180808153150.23444-11-brgl@bgdev.pl>
In-Reply-To: <20180808153150.23444-1-brgl@bgdev.pl>
References: <20180808153150.23444-1-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.
