+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
