+* Amlogic Secure Monitor
+
+In the Amlogic SoCs the Secure Monitor code is used to provide access to the
+NVMEM, enable JTAG, set USB boot, etc...
+
+Required properties for the secure monitor node:
+- compatible: Should be "amlogic,meson-gxbb-sm"
+
+Example:
+
+ firmware {
+ compatible = "simple-bus";
+
+ sm: secure-monitor {
+ compatible = "amlogic,meson-gxbb-sm";
+ };
+ };
+
+Example of the node using the secure monitor:
+
+ #include <dt-bindings/firmware/meson-sm.h>
+
+ ...
+
+ efuse: efuse {
+ compatible = "amlogic,meson-gxbb-efuse";
+ secure-monitor = <&sm>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ ...
+ };
