I don't think sdio needs disable-wp?

I thinks your are correct:

  disable-wp:
    $ref: /schemas/types.yaml#/definitions/flag
    description:
      When set, no physical write-protect line is present. This
      property should only be specified when the controller has a
      dedicated write-protect detection logic. If a GPIO is always used
      for the write-protect detection logic, it is sufficient to not
      specify the wp-gpios property in the absence of a write-protect
      line. Not used in combination with eMMC or SDIO.

It mention 'not used in combination with eMMC or SDIO', yet I see
multiple boards where disable-wp is currently used with eMMC and SDIO.

Do you have anything else to remark before I send a v4 with this prop
removed?

Jonas

Thanks,
Chukun
