[PATCH v3 0/8] dt-bindings: marvell: a38x: add solidrun armada 388 clearfog boards

Dear Maintainers,

The initially merged device-tree for Clearfog GTR devices contained
various subtle mistakes and omissions:

- missing board-specific compatible strings
- missing pinctrl entries
- missing second sfp connector
- invalid sfp loss-of-signal gpio
- mismatch of labels between dsa ports and enclosure

Most notably this had caused functional issues with the sfp connectors.

This patch-set first converts the armada-38x dt-bindings to yaml.
New bindings are added specifically for the Clearfog GTR boards,
and for the already in-tree clearfog base and pro boards' compatible strings.

Secondly pinctrl nodes are added for all referenced gpios for independence
from bootloader defaults. U-Boot is shared between armada-388 clearfog,
and armada-385 clearfog gtr.

Further remove an invalid io from the first sfp connector description,
and add descriptions for the secondary sfp connector which is driven
by dsa switch port number 9.

Finally labels of dsa switch ports were updated to match the enclosure.
That patch is not suitable for stable.
