Subject: [PATCH v2 2/4] drivers: of: initialize and assign reserved memory to
 newly created devices
Date: Mon, 14 Jul 2014 09:12:44 +0200
Message-id: <1405321966-28184-3-git-send-email-m.szyprowski@samsung.com>

References: <1405321966-28184-1-git-send-email-m.szyprowski@samsung.com>
Sender: linux-kernel-owner@vger.kernel.org

Use recently introduced of_reserved_mem_device_init() function to
automatically assign respective reserved memory region to the newly created
platform and amba device.
