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 <peng.fan@nxp.com> Reviewed-by: Rob Herring <robh@kernel.org> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> [sudeep.holla: reworded commit log and subject] Signed-off-by: Sudeep Holla <sudeep.holla@arm.com>
