Subject: [PATCH v2 1/2] dt-bindings: Add bindings for BrcmSTB SCMI mailbox driver
Date: Fri, 18 Sep 2020 18:15:14 -0400 [thread overview]
Message-ID: <20200918221520.21999-2-james.quinlan@broadcom.com> (raw)
In-Reply-To: <20200918221520.21999-1-james.quinlan@broadcom.com>
[-- Attachment #1.1: Type: text/plain, Size: 1506 bytes --]
Bindings are added. Only one interrupt is needed because
we do not yet employ the SCMI p2a channel.
