From 84631f37cc405dd6dcd566f9fa4e8a3ca2f03f76 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Mon, 17 Dec 2007 17:35:53 +1100 Subject: [POWERPC] Implement pci_set_dma_mask() in terms of the dma_ops PowerPC currently doesn't implement pci_set_dma_mask(), which means drivers calling it will get the generic version in drivers/pci/pci.c. The powerpc dma mapping ops include a dma_set_mask() hook, which luckily is not implemented by anyone - so there is no bug in the fact that the hook is currently never called. However in future we'll add implementation(s) of dma_set_mask(), and so we need pci_set_dma_mask() to call the hook. To save adding a hook to the dma mapping ops, pci-set_consistent_dma_mask() simply calls the dma_set_mask() hook and then copies the new mask into dev.coherenet_dma_mask.
