Features: * CPU: Cortex-A55 Octa (8 cores), up to 2 GHz * Memory interface: LPDDR4/4x 2 channels (12.8 GB/s) * SD/MMC: SD 3.0, eMMC5.1 DDR 8-bit * Modem: 4G LTE, 3G, GSM/GPRS/EDGE * RF: Quad GNSS, WiFi 5 (802.11ac), Bluetooth 5.0 * GPU: Mali-G52 MP1 * Codec: 1080p 60fps H64, HEVC, JPEG HW Codec * Display: Full HD+ (2520x1080)@60fps LCD * Camera: 16+5MP/13+8MP ISP, MIPI CSI 4/4/2, FD, DRC * Connectivity: USB 2.0 DRD, USI (SPI/UART/I2C), HSI2C, I3C, ADC, Audio This patch adds minimal SoC support. Particular board device tree files can include exynos850.dtsi file to get SoC related nodes, and then reference those nodes further as needed.
