Subject: [PATCH v2 12/13] ARM: davinci: mityomapl138: use aemif platform driver
Date:   Tue, 26 Jun 2018 11:25:36 +0200
Message-Id: <20180626092537.6737-13-brgl@bgdev.pl>
In-Reply-To: <20180626092537.6737-1-brgl@bgdev.pl>
References: <20180626092537.6737-1-brgl@bgdev.pl>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

We now support board files in the aemif driver. Register a platform
device instead of using the handcrafted API in mityomapl138.
