memory: mtk-smi: Get rid of need_larbid

2019-08-30T13:57:27+00:00

The "mediatek,larb-id" has already been parsed in MTK IOMMU driver.
It's no need to parse it again in SMI driver. Only clean some codes.
This patch is fit for all the current mt2701, mt2712, mt7623, mt8173
and mt8183.

After this patch, the "mediatek,larb-id" only be needed for mt2712
which have 2 M4Us. In the other SoCs, we can get the larb-id from M4U
in which the larbs in the "mediatek,larbs" always are ordered.

Correspondingly, the larb_nr in the "struct mtk_smi_iommu" could also
be deleted.

iommu/mediatek: Add mt2712 IOMMU support

2017-08-22T14:37:58+00:00

The M4U IP blocks in mt2712 is MTK's generation2 M4U which use the
ARM Short-descriptor like mt8173, and most of the HW registers are
the same.

The difference is that there are 2 M4U HWs in mt2712 while there's
only one in mt8173. The purpose of 2 M4U HWs is for balance the
bandwidth.

Normally if there are 2 M4U HWs, there should be 2 iommu domains,
each M4U has a iommu domain.
