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. - k _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
