title: Socionext UniPhier media I/O block (MIO) controller

maintainers:

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.
