Initial version of devicetree sources for NX1 SoC and boards. NX1 SoC belongs to the UniPhier armv8 architecture platform, and is designed for IoT and AI/ML application fields. This SoC has four Cortex-A53 cores and basically peripherals compatible with the previous UniPhier SoCs: PCIe Gen2, USB3.1/2.0, eMMC/SD, 1G Ethernet, UART, GPIO, FI2C, SPI, DMAC, and Video Out. The SOM is a small module that has only the peripherals necessary for booting: UART, FI2C for EEPROM, eMMC and SD. The reference board has other peripherals and external LED IC, and is in conjunction with SOM. PCIe works as an endpoint as default. The EVB is a standalone board that has all supported peripherals. PCIe works as a host controller as default. This SoC has only 190MB of PCIe space, so the possible endpoint devices are limited, but it is assumed that the reference board will be connected. This devicetree has two restrictions: - SD cards that works at 1.8V are not supported, because the power supply switching function is in the system controller and needs to be controlled by the driver. - This SoC has two USB ports, each with an HS-PHY and an SS-PHY, however, DWC3 can only specify one HS-PHY and one SS-PHY, so the PHYs on the second port are not currently specified.
