Subject: [PATCH 0/4] iommu/mediatek: Improve safety from dts

This patchset contains several improved patches:
[1/4] When mt8195 v7, I added a error log for dts parse fail, but it
doesn't ignore probe_defer case.(v6 doesn't have this err log.)
[2/4] Add a error path for MM dts parse.

[3/4][4/4] To improve safety from dts. Base on this:
https://lore.kernel.org/linux-mediatek/20211210205704.1664928-1-linux@roeck-us.net/

Base on linux-next-20220510.

Guenter Roeck (1):
  iommu/mediatek: Validate number of phandles associated with
    "mediatek,larbs"

Yong Wu (3):
  iommu/mediatek: Use dev_err_probe to mute probe_defer err log
  iommu/mediatek: Add error path for loop of mm_dts_parse
  iommu/mediatek: Improve safety for mediatek,smi property in larb nodes
