Subject: [PATCH v2 17/29] net: davinci_emac: use eth_platform_get_mac_address()
Date:   Fri, 10 Aug 2018 10:05:14 +0200
Message-Id: <20180810080526.27207-18-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 in eth_platform_get_mac_address() and all boards
have the mac-address cells defined. Stop getting the MAC from pdata
and use the dedicated helper.
