+  This node provides properties for configuring a Morse Micro MM81x device
+  connected via SDIO. The node shall be specified as a child node of an SDIO
+  controller.
+
+  It is recommended to declare a mmc-pwrseq on SDIO host above MM81x. Without
+  it, you may encounter issues during reboot. The mmc-pwrseq should be
+  compatible with mmc-pwrseq-simple. Please consult
+  Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.yaml for more
+  information.
