+
+maintainers:
+ - Andrew Jeffery <[email protected]>

+
+description: |+
+ The ASPEED SD/SDIO/eMMC controller exposes two slots implementing the SDIO
+ Host Specification v2.00, with 1 or 4 bit data buses, or an 8 bit data bus if
+ only a single slot is enabled.
+
+ The two slots are supported by a common configuration area. As the SDHCIs for
+ the slots are dependent on the common configuration area, they are described
+ as child nodes.
