Subject: [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:
https://lore.kernel.org/r/20240401-v6-8-0-net-next-mv88e6xxx-leds-v4-v3-0-221b3fa55f78@lunn.ch

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@...nel.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@...aro.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@...n.ch>)
- Link to v1: https://lore.kernel.org/r/20240321-cn9130-som-v1-0-711127a409ae@solid-run.com
