[PATCH v1 0/4] arm64: dts: imx93-var-som-symphony: align DTS with hw revision

[Stefano Radaelli]

This series adds support for several peripherals available on the
Variscite Symphony carrier board for the VAR-SOM-MX93 module.

The patches introduce:

- GPIO aliases cleanup to better expose available GPIOs
- FT5x06 capacitive touch controller
- USB1 (OTG, via PTN5150 Type-C controller) and USB2 (host-only) support
- LPSPI6 controller exposed on the expansion connector

These changes describe real hardware connections and make the exposed
interfaces available to user applications.

Tested on the Symphony board with a VAR-SOM-MX93.

[PATCH v1 1/4] arm64: dts: imx93-var-som-symphony: Update gpio aliases

[Stefano Radaelli]

This patch introduces 2 simple aliases:

Add a gpio3->gpio4 alias to allow flexible access to these GPIOs

Add a gpio4 alias for the PCA9534 GPIO expander.

[PATCH v1 2/4] arm64: dts: imx93-var-som-symphony: Add support for ft5x06 touch controller

[Stefano Radaelli]

The Symphony carrier board exposes a capacitive touch interface through an
FFC/FPC connector. This interface is wired to an FT5x06 touch controller
on the I2C bus when using Variscite’s 7-inch capacitive touch display.

This patch adds the FT5x06 device node to describe the actual hardware
connection and enables touch functionality on the Symphony board

[PATCH v1 3/4] arm64: dts: imx93-var-som-symphony: Add USB support

[Stefano Radaelli]

The Symphony carrier board includes a USB Type-C connector on the USB1
port through an NXP PTN5150 Type-C controller connected on the I2C bus.
The PTN5150 provides cable orientation detection and role switching
information to the USB controller.

This patch adds the PTN5150 node, its interrupt line, the required pin
muxing, and wires the controller to the USB1 OTG dual-role device using
the USB role-switch framework.

This patch adds also USB2 support, that remains in host-only mode,
matching the hardware capabilities of the Symphony board.
