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 Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Peng Fan <peng.fan@nxp.com> --- Documentation/devicetree/bindings/arm/arm,scmi.txt | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
