Subject[PATCH v2 2/3] dt-bindings: mailbox: Add interrupt-names to SPRD mailbox
Date
From: Orson Zhai <orson.zhai@unisoc.com>

We add an optional supp-outbox interrupt support to SPRD mailbox driver
with newly added sc9863a support and change to configure interrupts with
names in device tree files.
