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.
