+= Amlogic Meson GX eFuse device tree bindings =
+
+Required properties:
+- compatible: should be "amlogic,meson-gxbb-efuse"
+- clocks: phandle to the efuse peripheral clock provided by the
+ clock controller.
+- secure-monitor: phandle to the secure-monitor node
+
+= Data cells =
+Are child nodes of eFuse, bindings of which as described in
+bindings/nvmem/nvmem.txt
+
+Example:
+
+ efuse: efuse {
+ compatible = "amlogic,meson-gxbb-efuse";
+ clocks = <&clkc CLKID_EFUSE>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ secure-monitor = <&sm>;
+
+ sn: sn@14 {
+ reg = <0x14 0x10>;
+ };
+
+ eth_mac: eth_mac@34 {
+ reg = <0x34 0x10>;
+ };
+
+ bid: bid@46 {
+ reg = <0x46 0x30>;
+ };
+ };
+
+ sm: secure-monitor {
+ compatible = "amlogic,meson-gxbb-sm";
+ };
+
+= Data consumers =
+Are device nodes which consume nvmem data cells.
+
+For example:
+
+ eth_mac {
+ ...
+ nvmem-cells = <&eth_mac>;
+ nvmem-cell-names = "eth_mac";
+ };
