From 81186dc1610155fc96740a81aa4f0a8b3cbb7dfb Mon Sep 17 00:00:00 2001 From: Tanmay Shah Date: Fri, 6 Oct 2023 21:27:01 -0700 Subject: [PATCH] dt-bindings: zynqmp: add destination mailbox compatible Current dt-bindings does not contain compatible property for child mailbox node. Child mailbox nodes are used to represent destination (remote) IPI agents. The compatible property for all destination mailboxes must be required to identify the node. This addition of new required property does not break ABI as current driver does not use this compatible property but, new features in driver should use this property.
