[PATCH v6 0/7] arm64: dts: add description for solidrun cn9130 som and clearfog boards

[Josua Mayer]

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 v6:
- add device-tree for cn9132 clearfog and CEX-7 module
- add dt compatible for tla2021 adc
  --> I don't plan to submit a driver patch because I can't test it
  --> might share untested patch
- add dt property for swapping d+-/d- on cp110 utmi phy
  --> I plan to submit a driver patch, already prototyped
- removed duplicate node reference / status=okay for cp0_utmi from
  cn9131-cf-solidwan.dts
- rebased on 6.10-rc1
- Link to v5: https://lore.kernel.org/r/20240509-cn9130-som-v5-0-95493eb5c79d@solid-run.com

Changes in v5:
- replaced *-gpio properties with preferred *-gpios
  (Reported-by: robh at 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 at 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 at lunn.ch>)
- Link to v1: https://lore.kernel.org/r/20240321-cn9130-som-v1-0-711127a409ae@solid-run.com
