Samsung Exynos850 is ARMv8-based mobile-oriented SoC.
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.
