Subject: [PATCH 1/2] dt-bindings: zynqmp: add destination mailbox compatible
Date: Thu, 5 Oct 2023 10:08:24 -0700 [thread overview]
Message-ID: <20231005170825.3521669-1-tanmay.shah@amd.com> (raw)
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.
