+Subject: [PATCH] bus: fsl-mc: DMA configure to have force-dma as default
+
+Implicit dma setting from bus works when dma-ranges
+specified but not otherwise. We need to continue
+to go for force_dma as default for cases dma-ranges not
+specified. Example dynamic device tree generation for
+generic kvm virtual machines.
