[PATCH v8 3/5] ARM: dts: sunxi: add support for NetCube Systems Nagami SoM
Posted by Lukas Schmid 1 month ago 
NetCube Systems Nagami SoM is a module based around the Allwinner T113s
SoC. It includes the following features and interfaces:

- 128MB DDR3 included in SoC
- 10/100 Mbps Ethernet using LAN8720A phy
- One USB-OTG interface
- One USB-Host interface
- One I2S interface with in and output support
- Two CAN interfaces
- ESP32 over SDIO
- One SPI interface
- I2C EEPROM for MAC address
- One QWIIC I2C Interface with dedicated interrupt pin shared with EEPROM
- One external I2C interface
- SD interface for external SD-Card
