arm64: dts: rockchip: add RK3368-uQ7 (Lion) SoM
Browse files Browse the repository at this point in the history 
The RK3368-uQ7 SoM is a uQseven-compatible (40mm x 70mm, MXM-230
connector) system-on-module from Theobroma Systems, featuring the
Rockchip RK3368.

It provides the following feature set:
 * up to 4GB DDR3
 * on-module SPI-NOR flash
 * on-module eMMC (with 8-bit 1.8V interface)
 * SD card (on a baseboad) via edge connector
 * Gigabit Ethernet with on-module Micrel KSZ9031 GbE PHY
 * HDMI/eDP/MIPI-DSI/LVDS
 * MIPI-CSI
 * USB
   - 1x USB 2.0 dual-role
   - 1x USB 2.0 host
 * on-module STM32 Cortex-M0 companion controller, implementing:
   - low-power RTC functionality (ISL1208 emulation)
   - fan controller (AMC6821 emulation)
   - USB<->CAN bridge controller
