+* Firewall and privilege register settings in device tree
+
+Required properties:
+--------------------
+
+- compatible: should contain "intel,socfpga-secreg"
+- intel,offset-settings: 32-bit offset address of block register, and then
+ followed by 32-bit value settings.
+
+Example:
+--------
+
+ socfpga_secreg: socfpga-secreg {
+ compatible = "intel,socfpga-secreg";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ u-boot,dm-pre-reloc;
+
+ i_sys_mgr at ffd12000 {
+ reg = <0xffd12000 0x00000228>;
+ intel,offset-settings =
+ <0x00000020 0xff010000>,
+ <0x00000024 0xffffffff>;
+ u-boot,dm-pre-reloc;
+ };
+ };
