[PATCH v3 0/6] Add support for mt8167 display blocks

[Luca Leonardo Scorcia]

This series adds support for the display blocks on MediaTek mt8167.
Tested on Xiaomi Mi Smart Clock x04g.

The first patch just does some reordering of dts nodes with no other
changes as this makes later patches cleaner and easier to follow.

v3:
 - Added mt8167-dsi compatible to driver instead of changing the binding;
 - Resolved patch formatting issues.

v2:
 - Separate patch for mediatek,dsi-phy binding;
 - Separate patch for mt8167-dsi binding;
 - Simplified OF graph endpoints in mt8167.dtsi.

Luca Leonardo Scorcia (5):
  arm64: dts: mt8167: Reorder nodes according to mmio address
  dt-bindings: display: mediatek: Add compatibles for MediaTek mt8167
  dt-bindings: phy: mediatek,dsi-phy: Add support for mt8167
  arm64: dts: mediatek: mt8167: Add DRM nodes
  drm/mediatek: dsi: Add compatible for mt8167-dsi

Val Packett (1):
  gpu: drm: mediatek: ovl: add specific entry for mt8167

Claude review: Add support for mt8167 display blocks

[Claude Code Review Bot]

Overall Series Review

Subject: Add support for mt8167 display blocks
Author: Luca Leonardo Scorcia <l.scorcia@gmail.com>
Patches: 8
Reviewed: 2026-02-24T10:06:12.388349

---

This series adds display support for the MediaTek mt8167 SoC, covering DT bindings, devicetree nodes, and driver compatibles for the full DSI display pipeline. The series was tested on a Xiaomi Mi Smart Clock (x04g).

The series is well structured. Patch 1 reorders existing DTS nodes by MMIO address to keep the file clean before adding new display nodes. Patches 2 and 3 add DT binding entries for the various display blocks and the DSI PHY. Patch 4 is the main DTS patch adding all the DRM nodes with the complete display pipeline wiring. Patches 5 and 6 add driver support for the DSI controller and OVL block respectively.

The display pipeline wired in the DTS (OVL0 -> COLOR0 -> CCORR -> AAL0 -> GAMMA -> DITHER0 -> RDMA0 -> DSI0) correctly matches the existing `mt8167_mtk_ddp_main` path already defined in `mtk_drm_drv.c`. All compatibles used in the DTS have corresponding binding documentation and driver support (either via specific match entries added in this series, or via fallback compatibles to existing SoC entries). No significant issues were found across the series.

Claude review: arm64: dts: mt8167: Reorder nodes according to mmio address

[Claude Code Review Bot]

Patch Review

No issues found. The patch reorders existing DTS nodes to be sorted by their MMIO register addresses. I verified the resulting order is correct (0x10000000 through 0x16010000, monotonically increasing). The commit message accurately describes the change. Already has a Reviewed-by from AngeloGioacchino Del Regno.

Claude review: dt-bindings: display: mediatek: Add compatibles for MediaTek mt8167

[Claude Code Review Bot]

Patch Review

No issues found. This patch adds mt8167 compatible strings to seven display block binding schemas (AAL, CCORR, dither, gamma, OVL, RDMA, WDMA). Each new entry is placed in the correct position within the binding schema -- using fallback compatibles where appropriate (e.g., mt8173 for AAL/gamma/wdma, mt8183 for ccorr/dither, mt2701 for rdma) and standalone for OVL (which gets its own driver data in patch 6).

> +          - enum:
> +              - mediatek,mt8167-disp-ccorr
> +              - mediatek,mt8365-disp-ccorr
>            - const: mediatek,mt8183-disp-ccorr

The conversion from a single `const` to an `enum` for ccorr and wdma is the correct way to add another compatible that shares the same fallback. Already has Reviewed-by tags from both Krzysztof Kozlowski and AngeloGioacchino Del Regno.

Claude review: dt-bindings: phy: mediatek, dsi-phy: Add support for mt8167

[Claude Code Review Bot]

Patch Review

No issues found. Adds `mediatek,mt8167-mipi-tx` with `mediatek,mt2701-mipi-tx` as the fallback compatible, which matches how it is used in the DTS (patch 4). Already has Reviewed-by and Acked-by tags.

Claude review: arm64: dts: mediatek: mt8167: Add DRM nodes

[Claude Code Review Bot]

Patch Review

This is the main DTS patch adding all display-related nodes. The display pipeline is correctly wired:

> +			mmsys_main: endpoint@0 {
> +				reg = <0>;
> +				remote-endpoint = <&ovl0_in>;
> +			};

through to:

> +			port@0 {
> +				reg = <0>;
> +				dsi_in: endpoint {
> +					remote-endpoint = <&rdma0_out>;
> +				};
> +			};

This pipeline (mmsys -> OVL0 -> COLOR -> CCORR -> AAL -> GAMMA -> DITHER -> RDMA0 -> DSI) matches the `mt8167_mtk_ddp_main` array already in `mtk_drm_drv.c`. The ext path (mmsys endpoint@1 -> rdma1) is also present with rdma1 set to `status = "disabled"`.

The new nodes are correctly ordered by MMIO address, maintaining the ordering established in patch 1. The `mmsys` node appropriately gains a `power-domains` property. All blocks that need it have `iommus`, `power-domains`, `clocks`, and `interrupts` properties. The `dsi` and `mipi_tx` nodes are both `status = "disabled"` by default, to be enabled per board.

Claude review: drm/mediatek: dsi: Add compatible for mt8167-dsi

[Claude Code Review Bot]

Patch Review

No issues found. Adds a one-line compatible entry mapping `mediatek,mt8167-dsi` to the existing `mt2701_dsi_driver_data`, consistent with the commit message stating the mt8167 DSI controller is fully compatible with mt2701. The binding for `mt8167-dsi` already exists in the tree as a standalone compatible (not requiring a fallback), so this driver entry is the correct approach.

No issues found. The new `mt8167_ovl_driver_data` is identical to `mt8173_ovl_driver_data` except for `smi_id_en = true`:

> +static const struct mtk_disp_ovl_data mt8167_ovl_driver_data = {

This is the correct approach -- creating a separate driver data struct rather than trying to reuse mt8173's, since the `smi_id_en` difference is a real hardware distinction. The commit message appropriately cites Android kernel sources as the reference for this requirement. Already has a Reviewed-by from AngeloGioacchino Del Regno.
