Standard property to specify a Mailbox. Each value of
|
|
the mboxes property should contain a phandle to the
|
|
mailbox controller device node and an args specifier
|
|
that will be the phandle to the intended sub-mailbox
|
|
child node to be used for communication. See
|
|
Documentation/devicetree/bindings/mailbox/mailbox.txt
|
|
for more details about the generic mailbox controller
|
|
and client driver bindings. Also see
|
|
Documentation/devicetree/bindings/mailbox/ \
|
|
xlnx,zynqmp-ipi-mailbox.txt for typical controller that
|
|
is used to communicate with this System controllers.
