+ 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.

+ 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.
