[PATCH v3 0/4] Add larbid init routine for mediatek's gen1 smi larb driver

[PATCH v3 0/4] Add larbid init routine for mediatek's gen1 smi larb driver

[honghui.zhang]

From: Honghui Zhang <honghui.zhang@mediatek.com>

Mediatek's gen1 smi need the hardware larb-id to identify the offset for
the register which controls whether enable iommu for this larb.
In the commit 3c8f4ad85c4b ("memory/mediatek: add support for mt2701"),
the larbid was used without properly initialized. This patchset fixed
that.
Also include a patch which using the of_device_get_match_data helper to
simplify the code.
This patchset was base on 4.13-rc1.

Change since v2:
 - Using compatible strings of "mediatek,larb-id" instead of "mediatek,larbid"
   to make it a bit easier to read.
 - Put the v2 of the patch ("memory: mtk-smi: Use of_device_get_match_data helper")[1]
   in this patchset to make the changes easier for review.
 - Add the reivewer's tag in commit messages.

Change since v1:
 - Using mtk_smi_larb_gen to identify whether larbid was needed instead of
   checking hard code bindings.

[PATCH v3 2/4] memory: mtk-smi: add larbid handle routine

[honghui.zhang]

From: Honghui Zhang <honghui.zhang@mediatek.com>

In the commit 3c8f4ad85c4b ("memory/mediatek: add support for mt2701"),
the larb->larbid was added but not initialized.
Mediatek's gen1 smi need this hardware larbid information to get the
register offset which controls whether enable iommu for this larb.
This patch add the initialize routine for larbid.
