Subject: [PATCH v1 7/7] ARM: dts: sunxi: add support for NetCube Systems Nagami Keypad Carrier
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.
