[PATCH 0/2] Add support for EmbedFire LubanCat 4 board

[LemonFan-maker]

The LubanCat 4 is a single board computer from EmbedFire based on the
Rockchip RK3588S SoC.

This series adds a device tree binding compatible and a board DTS
covering the peripherals needed to boot into a userspace from eMMC or
SD card with networking:

  - UART2 debug console
  - RK806 SPI PMIC with the full regulator tree, and RK8602/RK8603
    fan53555-family supplies for the big CPU cluster and NPU
  - eMMC (HS400 enhanced strobe) and SD card (UHS SDR104)
  - GMAC1 with RGMII PHY on MDIO1 (JLSemi JL21xx, described via the
    generic clause-22 compatible)
  - HDMI0 output through hdptxphy0 and VOP2
  - PCIe 2.0 x1 (mini PCIe slot) via combphy0_ps
  - USB 2.0 host ports and one USB 3.0 host port
  - HYM8563 RTC on I2C0
  - On-board heartbeat LED and PWM fan header

Peripherals that require drivers or bindings not yet in mainline
(ES8388 audio codec, FUSB302-based USB-C, MIPI-CSI, NPU/VDEC/VENC,
DSI panels, IR receiver) are deliberately left out and can be added
in follow-up series.

The board has been tested on hardware: it boots to userspace over the
serial console from both eMMC and SD card, and Ethernet on GMAC1 comes
up and passes traffic.
