[PATCH v4 0/3] MediaTek MT8195 display binding

[PATCH v4 0/3] MediaTek MT8195 display binding

[Bo-Chen Chen]

Add this series to present MediaTek display binding for MT8195.
The reason I send this series is Jason and Nancy's binding patches are
never received by devicetree mail server.
Therefore, I help them to resend binding patches.

Changes for v4:
1. Rebase to v5.19-rc1 which iommu series is included.
2. Add my signed-off.

Changes for v3:
1. Fix rdma and ethdr binding doc.
2. Nancy's series: [1].
3. This series is based on linux-next: next-20220511.

Changes for v2:
1. This patch is based on linux next-20220506.
2. Jason's patches are accepted and I drop them.

During my review I missed that part. But your testing should not miss it
- please always run `make dt_bindings_check` and do not send code which
fails.

Best regards,
Krzysztof

Hello Krzysztof,

Sorry we did not check again for this.
And also thanks for your review.

I will modify this in next version.

BRs,
Rex
