[PATCH v2 0/3] Add Luckfox Omni3576 Carrier Board support for RK3576

[John Clark <inindev@gmail.com>]

This series adds device tree support for the Luckfox Omni3576 Carrier Board
with Core3576 Module, based on the Rockchip RK3576 SoC, enabling essential
functionality for booting Linux and basic connectivity. v1 was posted at:
https://lore.kernel.org/linux-rockchip/20250502205533.51744-1-inindev@gmail.com

Tested features (on Linux 6.15-rc4):
 - UART: Serial console operational
 - SD card: Mounts and reads/writes successfully
 - PCIe: NVMe SSD detected, mounted, and fully functional
 - Ethernet 0: Functional with RGMII PHY
 - USB 2.0: Host ports
 - RTC: Timekeeping and wake-up tested
 - LED: Heartbeat trigger works
 - eMMC: Enabled, not populated on tested board

The series includes the following patches:
 1. dt-bindings: vendor-prefixes: Add Luckfox vendor prefix
 2. dt-bindings: arm: rockchip: Add luckfox,omni3576 binding
 3. arm64: dts: rockchip: Add Luckfox Omni3576 Board support

The new DTS is covered by the existing ROCKCHIP ARCHITECTURE entry in MAINTAINERS.

I am aware of ongoing RK3576 upstreaming efforts (e.g., by Collabora) and
welcome feedback or collaboration to align with mainline driver development.

Changes in v2:
 - Enabled HDMI node per feedback from Heiko and Nicolas; untested due to
   upstream driver issues
 - Enabled Ethernet 1 node per Heiko's DT philosophy; untested due to
   suspected PHY driver or configuration issues
 - Clarified eMMC remains enabled but unpopulated on tested board, per Heiko
