Subject: [PATCH 2/2] arch/microblaze: Move dma_mask from of_device into pdev_archdata
Date: Thu, 11 Mar 2010 11:12:30 -0700 [thread overview]
Message-ID: <20100311181229.13022.81026.stgit@angua> (raw)
In-Reply-To: <20100311180952.13022.82694.stgit@angua>
By moving dma_mask into pdev_archdata, and adding archdata to
struct of_device, it makes it possible to substitute of_device
with struct platform_device, which is a stepping stone to
removing the of_platform bus entirely.
