Currently if the engine work, it always enable the power/clocks for smi-larbs/smi-common. This patch adds device_link for smi-common and M4U. then, if smi-common power is enabled, the M4U power also is powered on automatically. In this patch, a M4U connects with several smi-larbs and their smi-common always are the same, thus it adds the device-link once is enough. And the devicelink only is needed while m4u has power-domain.

When the engine work, the engine always enable the power and clocks for smi-larb/smi-common, then the M4U's power will always be powered on automatically via the device link with smi-common. Note: we don't enable the M4U power in iommu_map/unmap for tlb flush. If its power already is on, of course it is ok. if the power is off, the main tlb will be reset while M4U power on, thus the tlb flush while m4u power off is unnecessary, just skip it.

1: 4~8G; 2: 8-12G; 3: 12-16G; The bank number is (iova >> 32). We will preassign which bank the larbs belong to. currently we don't have a interface for master to adjust its bank number. Each a bank is a iova_region which is a independent iommu-domain. the iova range for each iommu-domain can't cross 4G.

That means the iova got from dma_alloc_attrs for that devices must locate in his special range. In this patch, we allocate a special iova_range for each a special requirement and create each a iommu domain for each a iova_range. meanwhile we still use one pagetable which support 16GB iova. After this patch, If the iova range of a master is over 4G, the master should: a) Declare its special dma_ranges in its dtsi node. For example, If we preassign the iova 4G-8G for vcodec, then the vcodec dtsi node should: dma-ranges = <0x1 0x0 0x1 0x0 0x1 0x0>; /* 4G ~ 8G */ b) Update the dma_mask: dma_set_mask_and_coherent(dev, DMA_BIT_MASK(33));
