From b953dceaddbf67c6915d257dd7c3ccf63fed5318 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Sun, 8 Mar 2020 21:24:38 +0800 Subject: [PATCH] dt-bindings: arm: Add smc/hvc transport for SCMI SCMI could use SMC/HVC as tranports. Since there is no standardized SMC/HVC function identifier for the same, we need to use vendor specific id. Add the same into the devicetree binding document. Also add arm,scmi-smc compatible string for smc/hvc transport Link: https://lore.kernel.org/r/1583673879-20714-2-git-send-email-peng.fan@nxp.com Signed-off-by: Peng Fan Reviewed-by: Rob Herring Reviewed-by: Florian Fainelli [sudeep.holla: reworded commit log and subject] Signed-off-by: Sudeep Holla --- Documentation/devicetree/bindings/arm/arm,scmi.txt | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/arm/arm,scmi.txt b/Documentation/devicetree/bindings/arm/arm,scmi.txt index dc102c4e4a78..1f293ea24cd8 100644 --- a/Documentation/devicetree/bindings/arm/arm,scmi.txt +++ b/Documentation/devicetree/bindings/arm/arm,scmi.txt @@ -14,7 +14,7 @@ Required properties: The scmi node with the following properties shall be under the /firmware/ node. -- compatible : shall be "arm,scmi" +- compatible : shall be "arm,scmi" or "arm,scmi-smc" for smc/hvc transports - mboxes: List of phandle and mailbox channel specifiers.
