Subject: [PATCH V5 1/2] dt-bindings: arm: arm,scmi: add smc/hvc transport
Date: Sun,  8 Mar 2020 21:24:38 +0800	[thread overview]
Message-ID: <1583673879-20714-2-git-send-email-peng.fan@nxp.com> (raw)
In-Reply-To: <1583673879-20714-1-git-send-email-peng.fan@nxp.com>

From: Peng Fan <peng.fan@nxp.com>

SCMI could use SMC/HVC as tranports. Since there is no
standardized id, we need to use vendor specific id. So
add into devicetree binding doc.

Also add arm,scmi-smc compatible string for smc/hvc transport
