Elsewhere in tree we have

Documentation/devicetree/bindings/clock/renesas,9series.yaml
      renesas,slew-rate:
        $ref: /schemas/types.yaml#/definitions/uint32
        enum: [ 2000000, 3000000 ]
        description: Output clock slew rate select in V/ns

atmel,at91-pio4-pinctrl.txt:
        - for microchip,sama7g5-pinctrl only:
                - slew-rate: 0 - disabled, 1 - enabled (default)

I guess having one solution would be best, and specifying real units
(V/ns) rather than fast/slow seems good to me.

Best regards,
