[PATCH v3 3/3] ARM: dts: sunxi: add support for NetCube Systems OpenNMC (dobermann)

[Lukas Schmid]

NetCube Systems OpenNMC is an open replacement for APC SmartSlot Management
Cards. It is based on the Nagami System-on-Module. It breaks out the
following interfaces:

- 10/100 Mbps Ethernet
- USB Type-C OTG using a TUSB320 (usb0)
- USB Type-C Console Port using a CH340 (uart3)
- USB Type-A Host with internal CH334 USB-Hub (usb1)
- MicroSD Slot with Card-Detect (mmc0)
- WiFi/Bluetooth using the modules built-in ESP32
- SmartSlot serial interface (uart4)
- DS3232 RTC with CR1220 Battery Backup
- Extension connector providing SPI,I2C,USB,CAN,UART for future use.

Re: [PATCH v3 3/3] ARM: dts: sunxi: add support for NetCube Systems OpenNMC (dobermann)

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The device tree source file is incorrectly added to the Makefile with a `.dts` extension instead of `.dtb`, which prevents the build system from generating the compiled device tree blob.

commit 050625703589dd3473dcaea2f70357c5bd2c45b5
Author: Lukas Schmid <lukas.schmid@netcube.li>

ARM: dts: sunxi: add support for NetCube Systems OpenNMC (dobermann)

This commit adds device tree support for the NetCube Systems OpenNMC board,
which acts as an open replacement for APC SmartSlot Management Cards based on
the Nagami System-on-Module.

[Severity: Low]
Does this target need to use the .dtb extension instead of .dts? Kbuild
expects the compiled device tree blob targets in the dtb-y lists to resolve
the compilation rules. Listing the source .dts file here might cause the build
system to skip compiling the new device tree blob entirely.
