Subject: [PATCH v4 04/18] ARM: davinci: dm644-evm: use nvmem lookup for mac address
Date: Fri, 29 Jun 2018 11:40:25 +0200	[thread overview]
Message-ID: <20180629094039.7543-5-brgl@bgdev.pl> (raw)
In-Reply-To: <20180629094039.7543-1-brgl@bgdev.pl>

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

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