12 description: |+
13 Media I/O block implemented on Socionext UniPhier SoCs is a legacy
14 integrated component of the stream type peripherals including USB2.0,
15 SD/eMMC, and MIO-DMAC.
16 Media I/O block has a common logic to control the component.
17
18 Recent SoCs have SD interface logic specialized only for SD functions
19 as a subset of media I/O block. See socionext,uniphier-sdctrl.yaml.
