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.
