    description: Read-strobe GPIO pin. Optional - driven high once and left alone if provided, since this bus only ever writes.

  max-transfer-bytes:
    type: int
    required: true
    description: |
      Maximum size in bytes of a single transfer over this bus. Sized for the attached
      panel's buffer (e.g. horizontal-resolution * vertical-resolution / N * bytes-per-pixel
      for an N-th sized partial buffer) - there is no bus-level default since it's entirely
      dependent on what's attached.
