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.
