Mediatek's gen1 smi need the hardware larbid 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.
This patchset was based on the v2 version of the patch:
memory: mtk-smi: Use of_device_get_match_data helper[1],
which was base on 4.13-rc1
[1] https://patchwork.kernel.org/patch/9864719
Change since v1:
- Using mtk_smi_larb_gen to identify whether larbid was needed instead of
checking hard code bindings.
Honghui Zhang (3):
memory: mtk-smi: add larbid handle routine
dt-bindings: mediatek: add descriptions for larbid
arm: dts: mediatek: add larbid property for larb
