[PATCH v5 0/4] arm64: dts: add description for solidrun cn9130 som and clearfog boards

SolidRun CN9130 SoM is a mostly pin-comptible replacement for Armada 388
SoM used in Clearfog and Clearfog Pro boards.

1. Add new binding for compatible strings closely matching the original.

2. Add device-tree includes for SoM and carrier shared design.

3. Add device-tree for both Clearfog Base and Pro.

While dtbs_check is happy with LED descriptions behind dsa switch,
functionally they require supporting code by Andrew Lunn:

NOTICE IN CASE ANYBODY WANTS TO SELF-UPGRADE:
CN9130 SoM has a different footprint from Armada 388 SoM.
Components on the carrier board below the SoM may collide causing
damage, such as on Clearfog Base.

Changes in v5:
- replaced *-gpio properties with preferred *-gpios
(Reported-by: robh@kernel.org)
- removed fixed-regulator regulator-oc-protection-microamp properties
This property is intended to set a configurable over-current limit to
a particular value. The physical component however is not
configurable, remove the property.
- kept all review tags since the changes were minor, hope that is okay
with everybody.
- Link to v4: https://lore.kernel.org/r/20240502-cn9130-som-v4-0-0a2e2f1c70d8@solid-run.com

Changes in v4:
- Picked up reviewed-by tags by Andrew Lunn.
- fixed a typo and changed 3-line comment into single-line comment
for clearfog-base/-pro dts, but kept review tags since change was
minor.
- Updated SFP led labels to use "sfp?:colour" without "color" property,
to avoid duplicate labels while reflecting they are each dual-colour.
- Link to v3: https://lore.kernel.org/r/20240414-cn9130-som-v3-0-350a67d44e0a@solid-run.com

Changes in v3:
- picked up acked-by for dt-bindings
- skipped acked-by for dts because additional changes were made:
- moved legacy netdev aliases to carrier dts
- fix status property style errors
- add pinctrl for secondary spi chip-select on mikrobus header (& som)
- specify spi bus frequency limits for som
- Added CN9131 SolidWAN board
- Link to v2: https://lore.kernel.org/r/20240404-cn9130-som-v2-0-3af2229c7d2d@solid-run.com

Changes in v2:
- rewrote dt bindings dropping unnecessary compatibles
(Reported-By: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>)
- added bindings for two additional boards (cn9131/9132)
support planned for the coming weeks, mostly serves
illustrational purposes, to understand cn913x variants
- cf-pro: add description for LEDs behind DSA switch
- cf-base: add description for LEDs behind PHYs
(Reported-By: Andrew Lunn <andrew@lunn.ch>)
- Link to v1: https://lore.kernel.org/r/20240321-cn9130-som-v1-0-711127a409ae@solid-run.com
