From cb6dc512b745292eaf123fedf437c211e27fb680 Mon Sep 17 00:00:00 2001 From: Grant Likely Date: Tue, 13 Apr 2010 16:12:59 -0700 Subject: [PATCH] arch/powerpc: Move dma_mask from of_device into pdev_archdata 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.
