Claude review: dt-bindigs: display: extend the LVDS codec with Triple 10-BIT LVDS Transmitter

[Claude Code Review Bot]

Patch Review

**Author:** David Heidelberg / Svyatoslav Ryhel

Adds `idt,v103` to the lvds-codec.yaml compatible enum as an LVDS encoder with the `lvds-encoder` fallback compatible.

```yaml
+              - idt,v103      # For the Triple 10-BIT LVDS Transmitter
```

- **Alphabetical ordering:** Correct. `idt,v103` sorts before `onnn,fin3385`.
- **Placement:** Correctly placed in the first `oneOf` block (LVDS encoders with `lvds-encoder` fallback), which is appropriate for a transmitter.
- **Comment style:** Follows the existing pattern of inline comments (`# For the ...`).

**Nit:** Subject says "dt-bindigs" — should be "dt-bindings".

No other issues.

Claude review: dt-bindigs: display: extend the simple bridge with MStar TSUMU88ADT3-LF-1 bridge

[Claude Code Review Bot]

Patch Review

**Author:** Svyatoslav Ryhel

Adds `mstar,tsumu88adt3-lf-1` to the simple-bridge.yaml compatible enum.

```yaml
+          - mstar,tsumu88adt3-lf-1
```

- **Alphabetical ordering:** Correct. `mstar,...` sorts after `dumb-vga-dac` and before `parade,ps185hdm`.
- **Placement:** In the standalone `enum` block (bridges without a fallback compatible), which is appropriate for this device.

**Nit:** Same subject typo — "dt-bindigs" should be "dt-bindings".

No other issues.

Claude review: drm/bridge: simple-bridge: Add support for MStar TSUMU88ADT3-LF-1

Patch Review

**Author:** Maxim Schwalm / Svyatoslav Ryhel

Adds the `of_device_id` entry for the MStar bridge in the simple-bridge driver.

```c
+	}, {
+		.compatible = "mstar,tsumu88adt3-lf-1",
+		.data = &(const struct simple_bridge_info) {
+			.connector_type = DRM_MODE_CONNECTOR_HDMIA,
+		},
```

- **Alphabetical ordering:** Correct. Placed after `asl-tek,cs5263` and before `parade,ps185hdm` in the `of_device_id` table.
- **Connector type:** `DRM_MODE_CONNECTOR_HDMIA` is correct for an HDMI bridge.
- **No timings:** The entry does not specify `.timings`, which means the bridge has no special timing constraints. This is consistent with other HDMI bridge entries in the table (e.g., `algoltek,ag6311`, `parade,ps185hdm`, `radxa,ra620`), and matches the cover letter description of a simple HDMI bridge.
- **Code style:** Matches the existing compound literal pattern used throughout the table.

No issues.

Overall Series Review

Subject: drm: bridge: add support for Triple 10-BIT
Author: Svyatoslav Ryhel <clamor95@gmail.com>
Patches: 4
Reviewed: 2026-03-04T07:49:52.137530

This is a straightforward 3-patch series adding device-tree bindings and driver support for two simple, non-programmable display bridges: the IDT V103 Triple 10-BIT LVDS Transmitter (used in Microsoft Surface RT) and the MStar TSUMU88ADT3-LF-1 HDMI bridge (used in ASUS Transformer AiO P1801-T).

The patches are minimal and clean. Alphabetical ordering is correctly maintained in all three files. The series already carries Reviewed-by tags from Robert Foss on all patches, plus Acked-by from Rob Herring (patch 1) and Conor Dooley (patch 2). This is v4, with the only change from v3 being a rebase onto v7.0.

**One recurring nit:** The subject prefix in patches 1 and 2 reads "dt-bindigs" instead of "dt-bindings". This typo has persisted across all four versions of the series.

No functional issues found. The series is ready to apply.
