[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?

Changes in v3:
- Add missing regulator-name property on fixed regulators
- Simplify regulator labels (reg_3v3_lvds_native -> reg_3v3_lvds,
  reg_3v3_lvds_bridge -> reg_3v3_dsi)
- Rename touch@ nodes to touchscreen@
- Link v2: https://lore.kernel.org/all/20260522132014.226721-13-ivitro@gmail.com/

Changes in v2:
- Add Ab tags
- Drop introduction of the LG LP156WF1 15.6" FHD dual-channel LVDS panel
- Drop migration of "logictechno,lt170410-2whc" to panel-lvds.yaml
- Link v1: https://lore.kernel.org/all/20260521150038.103538-17-ivitro@gmail.com/

[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 02/11] arm64: dts: ti: k3-am62-verdin: Add Toradex Capacitive Touch Display 10.1" LVDS

[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

[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.

Add device tree overlays for the Toradex OV5640 CSI Cameras on Verdin
CSI_1. Two variants are supported: the current CSI Camera Set 5MP OV5640
with a 27 MHz oscillator and the legacy CSI Camera Module 5MP OV5640
with a 24 MHz oscillator.

[Vitor Soares]

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

Add a device tree overlay enabling AM62 MCU_MCAN1 on the Toradex Verdin
Development Board with Verdin AM62 Mezzanine expansion board. MCU_MCAN1
is exposed on the Mezzanine CAN Header (J13), Pin 3 (CAN1_CONN_N) and
Pin 4 (CAN1_CONN_P).

[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 commit adds a device tree overlay for the Toradex Capacitive Touch
Display 10.1" on the Verdin DSI_1 interface. It configures the SN65DSI83
bridge, Riverdi LCD panel, and Ilitek ILI2132 touch controller, while
providing combined DTBs in the Makefile.

[Severity: Medium]
The comment indicates the interrupt pin is TOUCH_INT#, which typically denotes
an active-low signal.

Is IRQ_TYPE_EDGE_RISING the correct trigger here?

Triggering on a rising edge for an active-low signal means the interrupt will
fire only upon de-assertion. If the touch controller holds the line low until
the event is read via I2C, waiting for a rising edge could delay or prevent
the touch input event from being processed. Should this be configured as
IRQ_TYPE_EDGE_FALLING instead?

[Severity: Medium]
Does this interrupt type cause a deadlock with the touchscreen controller?

The comment indicates the hardware signal is active-low (TOUCH_INT#), which
is typical for I2C touch controllers like the ILI213x series. If the touch
controller asserts the interrupt by driving the line low and waits for the
host to read the data via I2C before releasing the line high, configuring
the host to wait for a rising edge could result in the interrupt handler
never being invoked.

Should this use an active-low or falling edge trigger instead?
