| 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. |
