[PATCH v1 00/15] arm64: dts: ti: k3-am62-verdin: Add display and peripheral overlays

[Vitor Soares]

From: Vitor Soares <vitor.soares@toradex.com>

This series adds device tree overlays, expanding the hardware support for
the Toradex Verdin AM62 SoM. The overlays target displays, cameras, audio,
and peripherals available through Toradex carrier boards and the accessory
ecosystem.

Display additions cover three interface types:
- native OLDI (LVDS) with Toradex Capacitive Touch Display 10.1" LVDS and
  LG LP156WF1 15.6" FHD dual-channel panels
- DSI-to-LVDS adapter based on the SN65DSI84 with Toradex Capacitive Touch
  Display 10.1" LVDS
- DSI driving Toradex Capacitive Touch Display 7" and 10.1" DSI.

The Riverdi vendor prefix and panel bindings required by the DSI overlay
patches are also added, along with an extension to the panel-lvds binding
to support lvds-dual-ports for dual-channel LVDS.

Non-display additions include OV5640 CSI camera support in 24 MHz and
27 MHz oscillator variants, NAU8822 Bridge Tied Load mode on the
Development Board, MCU_MCAN1 on the Mezzanine board low-speed header,
and MCU_UART0 reservation for the Cortex-M4F debug UART.

TI maintainers: patches adding the Riverdi vendor prefix, panel-lvds
bindings, and dual-channel LVDS support are required by the DTS patches.
Are you fine picking up the full series once those patches are acked by
the DT/display maintainers?

Am I missing a driver change in the series for this?
v7.1-rc1 has:

rg logictechno,lt170410-2whc
Documentation/devicetree/bindings/display/panel/panel-simple.yaml
210:      - logictechno,lt170410-2whc

drivers/gpu/drm/panel/panel-simple.c
5482:		.compatible = "logictechno,lt170410-2whc",

Additionally, please add a fixes tag.

Cheers,
Conor.

Claude review: dt-bindings: display: panel: Move Logic Technologies LT170410-2WHC to LVDS

[Claude Code Review Bot]

Patch Review

This moves the `logictechno,lt170410-2whc` compatible from `panel-simple.yaml` to `panel-lvds.yaml`.

**Potential regression concern**: If any existing DTS in-tree uses `logictechno,lt170410-2whc` as a simple panel (without `panel-lvds` as a fallback compatible), removing it from `panel-simple.yaml` could break existing board support. The patch author does use dual compatibles in the DTS patches (e.g., `"logictechno,lt170410-2whc", "panel-lvds"`), but existing upstream users may not.

**Indentation issue in panel-simple.yaml**: The removal leaves the comment for the next entry misaligned. In the original file:
```
      - logictechno,lt161010-2nhr
-        # Logic Technologies LT170410-2WHC 10.1" 1280x800 IPS TFT Cap Touch Mod.
-      - logictechno,lt170410-2whc
        # Logic Technologies LTTD800480070-L2RT 7" 800x480 TFT Resistive Touch Module
```
The comment `# Logic Technologies LTTD800480070-L2RT...` keeps its extra indentation (8 spaces vs the 6 spaces for the entry below it), but this was already the existing style in panel-simple.yaml, so it's fine.

The panel-lvds.yaml addition looks correctly alphabetically ordered.

[PATCH v1 02/15] arm64: dts: ti: k3-am62-verdin: Add Toradex DSI to LVDS adapter with 10.1" display

[Vitor Soares]

From: Vitor Soares <vitor.soares@toradex.com>

Add a device tree overlay for the Toradex DSI to LVDS Adapter with the
Toradex Capacitive Touch Display 10.1" LVDS. The adapter connects to the
Verdin DSI_1 interface. It is based on the Texas Instruments SN65DSI84
DSI-to-LVDS bridge and drives a LogicTechno LT170410-2WHC 10.1" WXGA LVDS
panel. Touch input is provided by an Atmel MaxTouch capacitive touch
controller.

Claude review: arm64: dts: ti: k3-am62-verdin: Add Toradex DSI to LVDS adapter with 10.1" display

[Claude Code Review Bot]

Patch Review

Structurally sound DSI-to-LVDS bridge overlay using `ti,sn65dsi84`.

**Minor**: The backlight node includes `pinctrl-0 = <&pinctrl_i2s_2_d_out_gpio>` but the pinctrl definition itself isn't in this overlay — it's presumably in the base DTS. This is fine for overlays that target a known base, but should be documented or verified.

**`Assisted-by: Claude:claude-sonnet-4.6`** — This is not a recognized kernel tag. It should either be `Co-developed-by:` with appropriate `Signed-off-by:` from the AI entity (which isn't practical), or simply noted in the commit message body. Kernel maintainers are likely to NAK this tag.

The touch controller on `&main_i2c1` at `0x4a` (`atmel,maxtouch`) uses `IRQ_TYPE_EDGE_FALLING` which is correct for MaxTouch.

[Vitor Soares]

From: Vitor Soares <vitor.soares@toradex.com>

Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
LVDS connected via Verdin AM62 OLDI on carrier boards exposing LVDS
interface (e.g., Mallow). The panel is a LogicTechno LT170410-2WHC 10.1"
WXGA IPS LCD and the touch input is provided by an Atmel MaxTouch
capacitive touch controller.

Claude review: arm64: dts: ti: k3-am62-verdin: Add Toradex Capacitive Touch Display 10.1" LVDS

[Claude Code Review Bot]

Patch Review

Native OLDI (LVDS) overlay. Generally clean.

**Minor style issue**: Extra space in pinctrl definition:
```c
AM62X_IOPAD(0x0098, PIN_INPUT,  7) /* (U23) GPMC0_WAIT0.GPIO0_37 */
```
The double space before `7` is inconsistent with the single space on the line above. Cosmetic only.

The touch controller here uses `&main_i2c2` (I2C_2_DSI), different from patch 2 which uses `&main_i2c1` — this is expected since LVDS vs DSI route through different carrier board interfaces.

Claude review: arm64: dts: ti: k3-am62-verdin: Add Toradex Capacitive Touch Display 10.1" DSI

[Claude Code Review Bot]

Patch Review

DSI overlay using `ti,sn65dsi83` bridge with Riverdi panel and ILI2132 touch.

**Observation**: This uses `ti,sn65dsi83` (the DSI83, single LVDS channel) while Patch 2 uses `ti,sn65dsi84` (the DSI84, dual LVDS support). This is correct — the 10.1" DSI display module contains a DSI83, while the standalone adapter uses a DSI84.

The touch controller uses `IRQ_TYPE_EDGE_RISING` for `ilitek,ili2132` — verify this matches the ILI2132 datasheet. The MaxTouch in patches 2/3 uses `IRQ_TYPE_EDGE_FALLING`. Different controllers can have different interrupt polarities, but this should be verified.

[PATCH v1 07/15] arm64: dts: ti: k3-am62-verdin: Add Toradex Capacitive Touch Display 7" DSI

[Vitor Soares]

From: Vitor Soares <vitor.soares@toradex.com>

Add a device tree overlay for the Toradex Capacitive Touch Display 7"
DSI on the Verdin DSI_1 interface. The display features an internal
Texas Instruments SN65DSI83 DSI-to-LVDS bridge driving a Riverdi
RVT70HSLNWCA0 7" WSVGA IPS TFT LCD panel. The touch input is provided
by an Ilitek ILI2132 capacitive touch controller.

Claude review: arm64: dts: ti: k3-am62-verdin: Add Toradex Capacitive Touch Display 7" DSI

[Claude Code Review Bot]

Patch Review

Very similar structure to Patch 6 but for the 7" Riverdi panel (`rvt70hslnwca0`). Uses the same bridge/touch hardware.

**Note**: This overlay and Patch 6 define identical label names (`panel_lvds_bridge_in`, `dsi_lvds_bridge_out`, `dsi_bridge_out`, `dsi_lvds_bridge_in`). Since these are mutually exclusive overlays (only one display at a time), this is correct.

Panel timing looks reasonable for 1024x600 @ ~51.2MHz.

[PATCH v1 08/15] arm64: dts: ti: k3-am62-verdin: Add NAU8822 Bridge Tied Load

[Vitor Soares]

From: Vitor Soares <vitor.soares@toradex.com>

Add a device tree overlay enabling Bridge Tied Load (BTL) mode on the
Nuvoton NAU8822 audio codec present on the Verdin Development Board.
In BTL mode, the two loudspeaker outputs are bridged to deliver higher
output power on the X28 speaker connector.

Claude review: arm64: dts: ti: k3-am62-verdin: Add Toradex OV5640 CSI Cameras

[Claude Code Review Bot]

Patch Review

Good factoring with common code in `k3-am625-verdin-ov5640.dtsi` and two thin overlays for 24MHz and 27MHz clock variants.

**Missing `regulator-min-microvolt` / `regulator-max-microvolt`** in the `regulator-camera` fixed regulator node. While optional for `regulator-fixed`, some DT validators may warn. Consider adding these.

**The `clk_ov5640_osc` fixed-clock node** is created without `clock-frequency` — it's set by each overlay. This is a clean pattern.

The camera node at `&main_i2c3` address `0x3c` is correct for OV5640. Supply names `AVDD`, `DOVDD`, `DVDD` all point to the same regulator, which is a common pattern when a single power rail feeds all camera supplies through the connector.

Claude review: arm64: dts: ti: k3-am62-verdin: Add Mezzanine with Toradex Display 10.1" LVDS

[Claude Code Review Bot]

Patch Review

Similar to Patch 3 but for the Mezzanine board. Uses `mcu_gpio0` instead of `main_gpio0` for backlight enable and touch GPIOs — correct for the Mezzanine routing.

**Missing pinctrl**: Unlike Patch 3, this overlay doesn't define pinctrl entries for the touch interrupt and reset GPIOs. The MCU GPIO pins may have default muxing, but if not, these pins may not function correctly. Worth checking whether the base DTS already configures these MCU GPIOs.

[PATCH v1 13/15] dt-bindings: display: panel-lvds: Add dual-channel LVDS support

[Vitor Soares]

From: Vitor Soares <vitor.soares@toradex.com>

The panel-lvds binding only supports single-channel panels.
Extend it to support dual-channel LVDS panels by referencing the
lvds-dual-ports schema when a ports container is present.

Ah, this is part of what sashiko was talking about I guess.
nvm that email so.
Why can't your new device go into panel-simple-lvds-dual-ports?

It was reviewed (by myself before Vitor did send the series). It is a
plain old mistake, unfortunately we cannot blame Claude for it.

Claude review: dt-bindings: display: panel-lvds: Add dual-channel LVDS support

[Claude Code Review Bot]

Patch Review

This is the most significant binding change. It modifies the `required:` section:

```yaml
-  - port
+
+oneOf:
+  - required:
+      - port
+  - required:
+      - ports
+
+if:
+  required:
+    - ports
+then:
+  $ref: /schemas/display/lvds-dual-ports.yaml#
```

This is architecturally correct — panels should support either single `port` or dual `ports`. The `if/then` conditional reference to `lvds-dual-ports.yaml` is the right mechanism.

**Ordering concern**: This patch (13/15) adds the dual-channel support, but Patch 15 already depends on it. The series ordering has these at 13 and 15, which is correct for application order. However, this binding patch should ideally come before any DTS that uses `ports` (Patch 15 is the only one), so the ordering is fine.

Claude review: arm64: dts: ti: k3-am62-verdin: Add Mezzanine with LG LP156WF1 LVDS panel

[Claude Code Review Bot]

Patch Review

Dual-channel LVDS overlay using `oldi0` + `oldi1` with `ti,companion-oldi` and `ti,secondary-oldi` properties. This is the AM62 dual OLDI pattern.

The panel node uses `ports` with `dual-lvds-odd-pixels` / `dual-lvds-even-pixels`, which correctly references the new schema from Patch 13.

**`data-mapping = "jeida-24"`** — different from the other panels which use `"vesa-24"`. This matches the LG LP156WF1 datasheet which uses JEIDA mapping.

**No `power-supply`** property on the panel node. The backlight has `enable-gpios` but the panel itself has no power supply reference. If the panel requires a separate power rail, this could be an issue. If it's always powered, it's fine.

The `dss_ports` node uses multiple endpoints (`endpoint@0`, `endpoint@1`) within a single `port@0` to drive both OLDI channels from the same DSS video port — this matches the AM62 hardware architecture where VP1 feeds both OLDI0 and OLDI1.

This is a well-structured device tree overlay series from Toradex for the Verdin AM62 SoM, adding support for multiple displays (LVDS, DSI, DSI-to-LVDS bridge), cameras, audio, CAN, and UART peripherals. The series is largely straightforward DTS work with a few binding changes.

**Positive aspects:**
- Good use of overlays (`.dtso`) for optional accessories — the right approach for carrier-board-specific peripherals
- Clean factoring of common OV5640 code into a shared `.dtsi`
- Dual-channel LVDS support for the LG panel is well-handled with the `lvds-dual-ports` schema reference
- Proper SPDX license headers, Signed-off-by, and documentation links throughout

**Concerns:**
- Heavy use of `Assisted-by: Claude:claude-sonnet-4.6` — not a standard kernel tag. Should use `Co-developed-by:` or drop it; DT maintainers may push back.
- Several patches use endpoint label names (`panel_lvds_bridge_in`, `dsi_lvds_bridge_out`, etc.) that will conflict if multiple overlays are ever applied simultaneously — inherent to overlays but worth noting.
- Patch 1 removes `logictechno,lt170410-2whc` from `panel-simple.yaml` and adds to `panel-lvds.yaml`, but there may be existing users relying on the panel-simple driver; this could be a regression.
- Patch 13 (dual-channel LVDS binding) changes the `required:` section in a way that affects all existing users of `panel-lvds` — removing `port` from `required` and using `oneOf` with `port` or `ports` is correct, but needs careful review by DT binding maintainers.
