arm64: dts: allwinner: a523: add Avaota-A1 router support
The Avaota A1 router board is an Open Source hardware board, designed by YuzukiHD. Pine64 produces some boards and sells them. It uses the Allwinner A527 or T527 SoC, and comes with the following features: - Eight ARM Cortex-A55 cores, Mali-G57 MC1 GPU - 1GiB/2GiB/4GiB LPDDR4 DRAM - AXP717 + AXP323 PMIC - Raspberry-Pi-2 compatible GPIO header - 1 USB 2.0 type A host port, 1 USB 3.0 type A host post - 1 USB 2.0 type C port (OTG + serial debug) - MicroSD slot - eMMC between 16 and 128 GiB - on-board 16MiB bootable SPI NOR flash - two 1Gbps Ethernet ports (via RTL8211F PHYs) - HDMI port - DP port - camera and LCD connectors - 3.5mm headphone jack - (yet) unsupported WiFi/BT chip - 1.3" LC display, connected via SPI - 12 V barrel plug for power supply Add the devicetree file describing the currently supported features.
