+Broadcom STB platforms Device Tree Bindings
+-------------------------------------------
+Boards with Broadcom Brahma15 ARM-based BCM7xxx SoC shall have the following
+properties.
+
+Required root node properties:
+
+    - compatible = "brcm,brcmstb-<chip_id>";
+
+Further, a node with the following compatible string shall be defined:
+
+    - compatible: "brcm,brcmstb-gen-ctrl-v1"
+
+brcmstb-gen-ctrl
+----------------
+This node describes the registers needed for reset and CPU power control.
+
+    - compatible: "brcm,brcmstb-gen-ctrl-v1"
+    - properties:
+        o reg = <rst-src-en-reg-base len
+                 sw-mstr-rst-reg-base len
+                 cpu-rst-cfg-reg-base len
+                 cpu-pwr-zone-ctrl-reg-base len
+                 stb-boot-hi-addr0-reg len>;
+
+example:
+/ {
+    model = "Broadcom STB";
+    compatible =  "brcm,brcmstb-7445";
+
+    /* snip */
+
+    gen-ctrl {
+        compatible = "brcm,brcmstb-gen-ctrl-v1";
+        reg = <0xf0404304 0x4
+               0xf0404308 0x4
+               0xf03e2578 0x4
+               0xf03e2488 0x10
+               0xf0452000 0x20>;
+    };
