+Broadcom STB platforms Device Tree Bindings
+-------------------------------------------
+Boards with Broadcom Brahma15-based BCM7xxx SOC shall have the following
+properties.
+
+Required root node properties:
+ - compatible = "brcm,brcmstb";
+
+Further, the following platform nodes shall be defined:
+
+ - sun-top-ctrl
+ - cpu-biu-ctrl
+ - hif-continuation
+
+sun-top-ctrl
+------------
+This node describes the register block which is used for generic reset control.
+
+ - compatible: "brcm,brcmstb-sun-top-ctrl"
+ - properties:
+ o reg = <base_of_sun_top_ctrl_regs length>;
+ o reset-source-enable-reg = <offset_from_base>;
+ o sw-master-reset-reg = <offset_from_base>;
+
+cpu-biu-ctrl
+------------
+This node describes the register block used for configuring the CPU complex.
+
+ - compatible: "brcm,brcmstb-cpu-biu-ctrl"
+ - properties:
+ o reg = <base_of_cpu_biu_ctrl_regs length>;
+ o cpu-reset-config-reg = <offset_from_base>;
+ o cpu0-pwr-zone-ctrl-reg = <offset_from_base>;
+
+hif-continuation
+----------------
+This node describes the registers for setting the starting PC for each CPU
core.
+
+ - compatible: "brcm,brcmstb-hif-continuation"
+ - properties:
+ o reg = <base_of_hif_continuation_regs length>;
+ o stb-boot-hi-addr0-reg = <offset_from_base>;
+
+example:
+
+/ {
+ model = "Broadcom STB";
+ compatible = "brcm,brcmstb";
+
+ /* snip */
+
+ sun-top-ctrl@f0404000 {
+ compatible = "brcm,brcmstb-sun-top-ctrl";
+ reg = <0xf0404000 0x51c>;
+ reset-source-enable-reg = <0x304>;
+ sw-master-reset-reg = <0x308>;
+ };
+
+ cpu-biu-ctrl@f0442400 {
+ compatible = "brcm,brcmstb-cpu-biu-ctrl";
+ reg = <0xf0442400 0x5b4>;
+ cpu-reset-config-reg = <0x178>;
+ cpu0-pwr-zone-ctrl-reg = <0x88>;
+ };
+
+ hif-continuation@f0452000 {
+ compatible = "brcm,brcmstb-hif-continuation";
+ reg = <0xf0452000 0x100>;
+ };
+
+ /* snip */
+};
