From 2189064795dc3fb4101e5c34d28c6b62b8a3bfd9 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 22 Sep 2014 11:48:31 +0100 Subject: arm64: Implement set_arch_dma_coherent_ops() to replace bus notifiers Commit 6ecba8eb51b7 (arm64: Use bus notifiers to set per-device coherent DMA ops) introduced bus notifiers to set the coherent dma ops based on the 'dma-coherent' DT property. Since the generic of_dma_configure() handles this property for platform and AMBA devices, replace the notifiers with set_arch_dma_coherent_ops().
