ARM: dts: sunxi: add support for NetCube Systems Nagami SoM
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 Signed-off-by: Lukas Schmid <lukas.schmid@netcube.li> Link: https://patch.msgid.link/20250831162536.2380589-4-lukas.schmid@netcube.li [wens@csie.org: fix up pinctrl names for i2c* and i2s_d*; fix indentation for gpio-line-names and rmii_pe_pins; fix "pre-magnetics" typo in comment] Signed-off-by: Chen-Yu Tsai <wens@csie.org>
