[PATCH v2 0/5] Add support for NetCube Systems Nagami SoM and its carrier boards

[Lukas Schmid]

This series adds support for the NetCube Systems Nagami SoM and its
associated carrier boards, the Nagami Basic Carrier and the Nagami Keypad
Carrier.

Changes in v2:
 - Squash the binding patches into one patch
 - Fix formatting of the phy node in the SoM dtsi
 - Add description on where the phy is located in the SoM dtsi
 - Fix the phy address in the SoM dtsi
 - Move the carrier bindings into the same description as enums

[PATCH v2 1/5] dt-bindings: arm: sunxi: Add NetCube Systems Nagami SoM and carrier board bindings

[Lukas Schmid]

The NetCube Systems Nagami is an System on Module base on the Allwinner
T113s SoC. It is intended to be used in low cost devices which require
simple layouts and low BOM cost.

The NetCube Systems Nagami Basic Carrier Board is a simple carrier for the
Nagami SoM. It is intended to serve as a simple reference design for a
custom implementation or just evaluating the module with other peripherals

The NetCube Systems Nagami Keypad Carrier is a custom board intended to
fit a standard Ritto Intercom enclosure and provides a Keypad, NFC-Reader
and Status-LED all controllable over Ethernet with PoE support.

[PATCH v2 4/5] ARM: dts: sunxi: add support for NetCube Systems Nagami Basic Carrier

[Lukas Schmid]

The NetCube Systems Nagami Basic Carrier is a Carrier for the Nagami SoM
It provides an ethernet port for the phy on the SoM and some USB-Ports.
All other interfaces and gpios are available on pinheader, except for the
SD-Interface which is available on a micro-sd slot.

[PATCH v2 5/5] ARM: dts: sunxi: add support for NetCube Systems Nagami Keypad Carrier

[Lukas Schmid]

The NetCube Systems Nagami Keypad Carrier uses the Nagami SoM and contains
a MCP23008 for connecting to a 4x3 matrix keypad and internal status led.
The I2C2 interface is connected to said MCP23008 and also a header for an
PN532 NFC-Module. It also provides a pin-header for a bi-color status led.
Ethernet with PoE support is available on a screwterminal after magnetics.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/next-20250704 (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

Can you please split this up, to have the MISO/MOSI/CLK signals under a
separate label, so that basic users can reuse this group?
CS should be a separate group, and I guess HOLD and WP can be in
another.

The rest looks alright, compared against the manual.

Cheers,
Andre
