Subject: [PATCH v4 1/2] dt-bindings: Add bindings for BrcmSTB SCMI mailbox driver
Date: Thu, 29 Oct 2020 15:59:06 -0400 [thread overview]
Message-ID: <20201029195913.5927-2-james.quinlan@broadcom.com> (raw)
In-Reply-To: <20201029195913.5927-1-james.quinlan@broadcom.com>
[-- Attachment #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.
