[PATCH v3 00/11] 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
- 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.

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 and panel-lvds
bindings are required by the DTS patches.
Are you fine picking up the full series once those patches are acked by
the DT/display maintainers?

[PATCH v3 01/11] 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.

[PATCH v3 05/11] arm64: dts: ti: k3-am62-verdin: Add Toradex Capacitive Touch Display 10.1" DSI

[Vitor Soares]

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

Add a device tree overlay for the Toradex Capacitive Touch Display 10.1"
on the Verdin DSI_1 interface. The display features an internal
Texas Instruments SN65DSI83 DSI-to-LVDS bridge driving a Riverdi
RVT101HVLNWC00 10.1" WXGA (1280x800) IPS TFT LCD panel. The touch input
is provided by an Ilitek ILI2132 capacitive touch controller.

The overlay is also combined with the Verdin AM62 Dahlia carrier board
device trees to provide ready-to-use DTBs in both WiFi and non-Wifi SoM
variants.

[PATCH v3 07/11] 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.

[PATCH v3 11/11] arm64: dts: ti: k3-am62-verdin: Add Mezzanine with Toradex Display 10.1" LVDS

[Vitor Soares]

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

Add a device tree overlay enabling the Toradex Capacitive Touch Display
10.1" LVDS on the Verdin Development Board with Verdin AM62 Mezzanine
expansion board. The panel connects via the AM62 OLDI0 on the Mezzanine
LVDS interface (J10). 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.

Changes in v3:
- Add missing regulator-name property on fixed regulators
- Simplify regulator labels
- Rename touch@ nodes to touchscreen@

Changes in v2:
- Use panel-simple compatible form

This is an 11-patch series from Vitor Soares (Toradex) adding device tree overlays for various peripherals on the Toradex Verdin AM62 SoM. The series covers display overlays (LVDS native, DSI-to-LVDS bridge, DSI panels), camera (OV5640 CSI), audio (NAU8822 BTL), CAN, and UART reservation. It also adds the Riverdi vendor prefix and panel-lvds bindings needed by the DSI display patches.

**Overall assessment: The series is well-structured and largely correct.** The overlays follow existing patterns in the TI DTS tree, Makefile additions are properly sorted, and the overlay approach (`.dtso` files with `#include` for shared code) is clean. The v3 changes (regulator-name, touchscreen@ rename, label simplification) address earlier review feedback well.

A few observations:

1. All patches carry `Assisted-by: Claude:claude-sonnet-4.6` — this is an informal tag not recognized by the kernel community. This should either be dropped or changed to a recognized trailer format if there is emerging consensus on AI attribution.

2. The DSI display overlays (patches 5 and 6) share nearly identical bridge and touch controller sections. This is acceptable for overlays since they're standalone, but it could be considered whether a shared `.dtsi` approach (like the OV5640 camera patches use) would be cleaner.

3. The series ordering puts DTS patches before the binding patches they depend on (patches 5/6 use `riverdi,*` compatibles introduced in patches 3/4). While `dtbs_check` won't pass until all patches are applied, git bisectability of the DT compilation itself is fine since these are new files. The cover letter acknowledges this cross-subsystem dependency.

No blocking issues found.

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

[Claude Code Review Bot]

Patch Review

This overlay adds a DSI-to-LVDS adapter (SN65DSI84) with a LogicTechno LT170410-2WHC panel. The structure looks correct.

- The `backlight-pwm3` node references `pinctrl_i2s_2_d_out_gpio` for the backlight enable GPIO — this pinctrl is defined in `k3-am62-verdin.dtsi` (line 393). Good.

- The SN65DSI84 bridge node uses `port@0` (input) and `port@2` (output), which matches the TI SN65DSI84 binding (port 0 = DSI input, port 2 = LVDS output, single-link). Correct.

- The `touchscreen@4a` uses `pinctrl_dsi1_int` and `pinctrl_i2s_2_bclk_gpio`, both defined in the base dtsi. Good.

- Minor: The composite DTB test entry pairs this overlay only with `k3-am625-verdin-wifi-dev.dtb`. The cover letter says it also works on Dahlia. Consider adding a Dahlia composite DTB as well, or document that this is just a build-test representative.

**No blocking issues.**

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

[Claude Code Review Bot]

Patch Review

This overlay drives the same panel (LT170410-2WHC) but via the native AM62 OLDI output rather than a DSI bridge, for carrier boards like Mallow.

- The overlay correctly defines `pinctrl_i2s_2_d_in_gpio` and `pinctrl_i2s_2_sync_gpio` in `&main_pmx0` within the overlay itself. These pin controls are NOT in the base dtsi, so they must be defined here. This is correct — they're only needed when this specific overlay is applied.

- The `reg_3v3_lvds` fixed regulator has `regulator-name = "+V3.3_LVDS"` — good, this was a v3 fix.

- The touchscreen is on `&main_i2c2` (Verdin I2C_2_DSI), which is the correct bus for display touch on this platform.

- The `backlight-pwm2` uses `epwm0 1` (PWM_2 / SODIMM 16), while patch 1 uses `epwm1 0` (PWM_3_DSI / SODIMM 19). The different PWM channels match the different Verdin signal routing for LVDS vs DSI. Correct.

**No blocking issues.**

Claude review: dt-bindings: display: panel-lvds: Add Riverdi RVT70HSLNWCA0 and RVT101HVLNWC00

[Claude Code Review Bot]

Patch Review

Adds two Riverdi panel compatibles to the panel-lvds binding. Already has `Acked-by: Conor Dooley`.

- The alphabetical placement between `jenson` and `samsung` is correct (`j` < `r` < `s`). Verified against the existing file.

- Note that the entries within the Riverdi block list the 10.1" panel first (`rvt101hvlnwc00`) then the 7" (`rvt70hslnwca0`). This is correct alphabetical ordering by the compatible string value.

**No issues.**

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

[Claude Code Review Bot]

Patch Review

This is a DSI display overlay using an SN65DSI83 bridge (note: SN65DSI**83**, single-channel LVDS, vs the SN65DSI**84** dual-channel in patch 1). The panel is a Riverdi RVT101HVLNWC00.

- The panel node uses `compatible = "riverdi,rvt101hvlnwc00", "panel-lvds"` with full `panel-timing` block. This is the correct pattern for `panel-lvds` compatible bindings — a vendor-specific first compatible string with `panel-lvds` as fallback, accompanied by explicit timing.

- Panel timing looks reasonable for a 1280x800@60Hz panel: `clock-frequency = <72400000>` (~72.4 MHz) with the specified blanking intervals yields approximately 60 Hz.

- The touchscreen uses `ilitek,ili2132` at address `0x41` with `IRQ_TYPE_EDGE_RISING` — this differs from patch 1's Atmel MaxTouch at `0x4a` with `IRQ_TYPE_EDGE_FALLING`. The different touch controllers and interrupt polarities match the different display products. Correct.

- This overlay and patch 6 (7" DSI) would conflict if both were applied simultaneously (same label names `backlight_pwm3`, `dsi_bridge_out`, `dsi_lvds_bridge_in`, `dsi_lvds_bridge_out`, `panel_lvds_bridge_in`). This is expected and fine — they're mutually exclusive overlays for the same DSI port.

- Composite DTB entries are added for both WiFi and non-WiFi Dahlia variants. Good.

**No blocking issues.**

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

[Claude Code Review Bot]

Patch Review

Nearly identical to patch 5 but for the 7" Riverdi RVT70HSLNWCA0 panel. The key differences:
- `compatible = "riverdi,rvt70hslnwca0", "panel-lvds"`
- Resolution: 1024x600 vs 1280x800
- `clock-frequency = <51200000>` (~51.2 MHz) — correct for 1024x600@60Hz
- Physical dimensions: `height-mm = <86>; width-mm = <154>` vs 136/217mm for the 10.1"

- The touchscreen is identical to patch 5 (`ilitek,ili2132` at `0x41`). This makes sense as both DSI displays use the same touch controller.

- Only a composite DTB with `k3-am625-verdin-wifi-dev.dtb` is added. Patch 5 also added Dahlia composites (both WiFi and non-WiFi). **Consider adding Dahlia composite DTBs here too for consistency**, since the commit message says it works on "Dahlia (X17) and Development Board (X48)."

**Minor: Missing Dahlia composite DTB entries compared to patch 5.**

Claude review: arm64: dts: ti: k3-am62-verdin: Add NAU8822 Bridge Tied Load

[Claude Code Review Bot]

Patch Review

Very simple overlay — just adds `nuvoton,spk-btl` to the existing `&nau8822_1a` node. The `nuvoton,spk-btl` property is documented in `nuvoton,nau8822.yaml` and the label `nau8822_1a` is defined in `k3-am62-verdin-dev.dtsi`.

- The overlay filename includes `dev` prefix (`k3-am625-verdin-dev-nau8822-btl.dtso`) correctly indicating this is Development Board specific, since the NAU8822 is on the dev board only.

**No issues.**

Patch Review

Simple overlay setting `status = "reserved"` on `&mcu_uart0`.

- Using `status = "reserved"` is the correct way to indicate a resource is claimed by another processor (Cortex-M4F) and should not be used by Linux.

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

[Claude Code Review Bot]

Patch Review

Good use of a shared `.dtsi` file with two thin `.dtso` wrappers that only override `clock-frequency` (27 MHz vs 24 MHz). Clean factoring.

- The `clk_ov5640_osc` fixed-clock node is defined without a `clock-frequency` — it must be set by the including `.dtso`. This works because overlays are compiled as complete units, and the `.dtsi` is included into the `.dtso` before compilation.

- The `regulator_camera` uses `gpio = <&main_gpio0 42 GPIO_ACTIVE_HIGH>` with `enable-active-high` — correct for a GPIO-controlled power switch.

- All three OV5640 supply rails (`AVDD`, `DOVDD`, `DVDD`) point to `&regulator_camera`. This is a simplification — the OV5640 datasheet specifies different voltages for each rail (2.8V analog, 1.8V IO, 1.5V digital core). This is common in DTS for modules where a single power control GPIO gates all rails through the module's on-board regulators.

- The camera endpoint specifies `data-lanes = <1 2>` (2-lane CSI-2) and `bus-type = <4>` (CSI-2 D-PHY) on both sides of the link. Correct.

**No issues.**

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

[Claude Code Review Bot]

Patch Review

This overlay is very similar to patch 2 (native LVDS) but targets the Mezzanine expansion board rather than the Mallow carrier. Key differences:

- Backlight enable uses `mcu_gpio0 4` (Verdin GPIO_4 / SODIMM 212) instead of `main_gpio0 34` (Verdin I2S_2_D_OUT / SODIMM 46). This matches the Mezzanine board's different LVDS backlight wiring.

- Touch interrupt/reset use `mcu_gpio0` pins 3 and 2 (Verdin GPIO_3/GPIO_2) instead of `main_gpio0` pins 37 and 33. Again matches the Mezzanine's different touch routing.

- The backlight node does **not** have `pinctrl-names`/`pinctrl-0` properties, unlike patch 2. This is correct because the `mcu_gpio0` pins don't require explicit pinmux configuration on AM62 (they default to GPIO function).

- The touchscreen node also lacks `pinctrl-names`/`pinctrl-0` for the same reason. Correct.

**No blocking issues.**
