[PATCH v7 0/2] Add support for Variscite DART-MX95 and Sonata board

[PATCH v7 0/2] Add support for Variscite DART-MX95 and Sonata board

[Stefano Radaelli]

This patch series adds support for the Variscite DART-MX95 system on
module and the Sonata carrier board.

The series includes:
- Device tree bindings documentation for both SOM and carrier board
- SOM device tree with on-module peripherals
- Sonata carrier board device tree with board-specific features

The implementation follows the standard SOM + carrier board pattern
where the SOM dtsi contains only peripherals mounted on the module,
while carrier-specific interfaces are enabled in the board dts.

v7:
- Order nodes in symphony dts
v6:
- Order by node name instead of by label
v5:
- Fix newlines and nodes order
v4:
- Fix typo in spacing
- Remove vpu and cm7 reserved memory
- Add GPIO_OPEN_DRAIN to i2c gpios
- Move pinmux to eof
v3:
- Fix specific node names with generic ones
- Remove fixed-link property for SFP
- Audio regulator cleanup
v2:
- Add SFP cage node for enetc_port2 following sff,sfp.yaml binding

[PATCH v7 1/2] arm64: dts: freescale: Add support for Variscite DART-MX95

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r@variscite.com>

Add device tree support for the Variscite DART-MX95 system on module.
This SOM is designed to be used with various carrier boards.

The module includes:
- NXP i.MX95 MPU processor
- Up to 16GB of LPDDR5 memory
- Up to 128GB of eMMC storage memory
- Integrated 10/100/1000 Mbps Ethernet Transceiver
- Codec audio WM8904
- WIFI6 dual-band 802.11ax/ac/a/b/g/n with optional 802.15.4 and Bluetooth

Only SOM-specific peripherals are enabled by default. Carrier board
specific interfaces are left disabled to be enabled in the respective
carrier board device trees.

[PATCH v7 2/2] arm64: dts: imx95-var-dart: Add support for Variscite Sonata board

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r@variscite.com>

Add device tree support for the Variscite Sonata carrier board with
the DART-MX95 system on module.

The Sonata board includes
- uSD Card support
- USB ports and OTG
- Additional Gigabit Ethernet interface
- 10Gb Ethernet SFP+ connector
- Uart interfaces
- OV5640 Camera support
- GPIO Expanders
- RTC module
- TPM module
- PCIE support

Signed-off-by: Stefano Radaelli <stefano.r@variscite.com>
---
v7:
- Order gpio and regulator nodes
v6:
- Order by node name instead of by label
v5:
- Fix newlines and nodes order
v4:
- Add GPIO_OPEN_DRAIN to i2c gpios
- Move pinmux to eof
v3:
- Fix specific node names with generic ones
- Remove fixed-link property for SFP
v2:
- Add SFP cage node for enetc_port2 following sff,sfp.yaml binding

Can you run https://github.com/lznuaa/dt-format for new file to easy
track and check by script later.

I applied with below change
- update copywrite to 2026
- move reg after compatible at ethernet phy node
- order button-n,

Next time,  run dt-format,  keep node orders, just adjust some property.
I will enhance script check graduatelly.

How do you know that the correct copyright year is 2026?
The copyright years does not change to today just because it is the year
it was submitted.

I think that you should refrain yourself for doing these kind of changes
to the code when you apply patches.

Thanks

At least it should include 2026 because it is new files in kernel tree.

If original owner have concern, I can update it in my tree.

Hi Francesco, hi Frank,

thanks for the clarification.

In this specific case, I'm fine with keeping 2026 for these new files
introduced in the kernel tree.

Thank you all for taking care of this!

Stefano

The copyright year is not changing nor being updated just because you
are adding the file to the linux kernel tree.

It is impossible zero modify before submit patch. If update copywrite year,
it needs include current years, I omit it when review it and find at apply.

And original owner Stefano Radaelli's agree on update to 2026.
