Subject: [PATCH 0/3] driver core: Add ability for arch code to setup pdev_archdata
Date: Thu, 5 Aug 2010 10:15:44 -0500 [thread overview]
Message-ID: <1281021347-1278-1-git-send-email-galak@kernel.crashing.org> (raw)
On PPC we need to set the dma_mask pointer for platform_devices to point to
the pdev_archdata. We can't wait for a bus_notifier as we need the dma_mask
setup before the platform_device_add happens so that the bus_notifiers can
check the dma_mask to determine if we need things like the SWIOTLB dma_ops.
The patch series introduces an arch specific call out (arch_setup_pdev_archdata)
and provide an implementation on PPC to handle our specific issue.
