[PATCH v3 0/3] Add support for Firefly Core-PX30-JD4 SoM & baseboard

[Christopher Obbard <chris.obbard@collabora.com>]

This adds support for the PX30-based Core-PX30-JD4 system-on-module from
Firefly and includes support for the SoM in combination with the
Firefly MB-JD4-PX30 baseboard.

---
Changes in v3:
- Rename px30-firefly-jd4.dts=>px30-firefly-jd4-core-mb.dts to follow
  the existing <SoC>-<brand>-<SoM>-<carrier>.dts pattern.
- Change the compatible names to firefly,px30-jd4-core and
  firefly,px30-jd4-core-mb to follow the above pattern.
- Adjust some grammatical errors (with=>on).
- Link to v2: https://lore.kernel.org/r/20240717-rockchip-px30-firefly-v2-0-06541a5a5946@collabora.com

Changes in v2:
- Split into two separate files: dtsi for the SoM and dts for the carrier.
- Change devicetree compatible to match SoM/carrier split.
- Change device names to better match vendor's name.
- Properly model baseboard & SoM regulators.
- Properly model baseboard recovery key.
- Remove DSI panel (& related nodes) since "sitronix,st7703" compatible
  is undocumented & hardware is unavailable.
- Remove unused audio-related nodes.
- Remove unused UART nodes.
- Remove unused PMIC pinctrl nodes.
- Add node for baseboard LEDs.
- Link to v1: https://lore.kernel.org/r/20240716-rockchip-px30-firefly-v1-0-60cdad3023a3@collabora.com
