+description: |
+  An MSI controller signals interrupts to a CPU when a write is made
+  to an MMIO address by some master. An MSI controller may feature a
+  number of doorbells.

+properties:
+  "#msi-cells":
+    description: |
+      The number of cells in an msi-specifier, required if not zero.
+
+      Typically this will encode information related to sideband data,
+      and will not encode doorbells or payloads as these can be
+      configured dynamically.
+
+      The meaning of the msi-specifier is defined by the device tree
+      binding of the specific MSI controller.
