Keep the nodename the same as in pinctrl.

remove
A new node is already okay.

use consistant nodename with pinctrl

fault_led: fault-led {}
status_led: status-led {}

  # The first form is preferred, but fall back to just 'led' anywhere in the
  # node name to at least catch some child nodes.

none is not in the list off approved options, see below

recheck led common.yaml

panic is a costum trigger
use standard trigger only
or use function property

  linux,default-trigger:
    description:
      This parameter, if present, is a string defining the trigger
assigned to
      the LED.
    $ref: /schemas/types.yaml#definitions/string

    enum:
      - backlight
      - default-on
      - heartbeat
      - disk-activity
      - ide-disk
      - timer
      - pattern

move things that start with # down the list

sort order is:
compatible
reg
interrupts
the rest
