description: |+

  Media I/O block implemented on Socionext UniPhier SoCs is a legacy

  integrated component of the stream type peripherals including USB2.0,

  SD/eMMC, and MIO-DMAC.

  Media I/O block has a common logic to control the component.

  Recent SoCs have SD interface logic specialized only for SD functions

  as a subset of media I/O block. See socionext,uniphier-sdctrl.yaml.
