[PATCH 2/3] arm64: dts: rockchip: add PX30-µQ7 (Ringneck) SoM with Haikou baseboard

From: Quentin Schulz
Date: Thu Sep 22 2022 - 06:12:58 EST

From: Quentin Schulz <quentin.schulz@xxxxxxxxxxxxxxxxxxxxx>

The PX30-uQ7 (Ringneck) SoM is a µQseven-compatible (40mmx70mm, MXM-230
connector) system-on-module from Theobroma Systems[1], featuring the
Rockchip PX30.

It provides the following feature set:
* up to 4GB DDR4
* up to 128GB on-module eMMC (with 8-bit 1.8V interface)
* SD card (on a baseboard) via edge connector
* Fast Ethernet with on-module TI DP83825I PHY
* MIPI-DSI/LVDS
* MIPI-CSI
* USB
- 1x USB 2.0 dual-role
- 3x 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
* on-module Espressif ESP32 for Bluetooth + 2.4GHz WiFi
* on-module NXP SE05x Secure Element
