From 1f5c69aa51f9c7c8d2a5c2e4dc339f6c7d5c15cd Mon Sep 17 00:00:00 2001 From: Murali Karicheri Date: Tue, 3 Mar 2015 12:52:09 -0500 Subject: of: Move of_dma_configure() to device.c to help re-use Move of_dma_configure() to device.c so it can be re-used for PCI devices to obtain DMA configuration from DT. Also add a second argument so that for PCI, the DT node of root bus host bridge can be used to obtain the DMA configuration for the slave PCI device.
