Add device tree for the Luckfox Omni3576 Carrier Board with Core3576 Module, powered by the Rockchip RK3576 SoC with four Cortex-A72 cores, four Cortex-A53 cores, and a Mali-G52 MC3 GPU. This initial implementation enables essential functionality for booting Linux and basic connectivity. Supported and tested features: - UART for serial console - SD card for storage - PCIe with NVMe SSD (detected, mounted, and fully functional) - USB 2.0 host ports - RK806 PMIC for power management - RTC with timekeeping and wake-up - GPIO-controlled LED with heartbeat trigger - eMMC (enabled, not populated on tested board) The device tree provides a foundation for further peripheral support, such as WiFi, MIPI-DSI, HDMI, and Ethernet, in future updates. Tested on Linux 6.15-rc4 Based on the Luckfox SDK, which derives from Rockchip’s SDK examples, with relevant changes to align with upstream Linux.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
