 Required root node property:
 
 compatible: should be "brcm,bcm63138"
+
+An optional Boot lookup table Device Tree node is required for secondary CPU
+initialization as well as a 'resets' phandle to the correct PMB controller as
+defined in reset/brcm,bcm63138-pmb.txt for this secondary CPU, and an
+'enable-method' property.
+
+Required properties for the Boot lookup table node:
+- compatible: should be "brcm,bcm63138-bootlut"
+- reg: register base address and length for the Boot Lookup table
+
+Optional properties for the primary CPU node:
+- enable-method: should be "brcm,bcm63138"
+
+Optional properties for the secondary CPU node:
+- enable-method: should be "brcm,bcm63138"
+- resets: phandle to the relevant PMB controller, one integer indicating the internal
+  bus number, and a second integer indicating the address of the CPU in the PMB
+  internal bus number.
+
+Example:
+
+       cpus {
+               cpu@0 {
+                       compatible = "arm,cotex-a9";

+=======
+reboot
+------
+Two nodes are required for software reboot: a timer node and a syscon-reboot node.
+
+Timer node:
+
+- compatible: Must be "brcm,bcm6328-timer", "syscon"
+- reg: Register base address and length
+
+Syscon reboot node:
+
+See Documentation/devicetree/bindings/power/reset/syscon-reboot.txt for the
+detailed list of properties, the two values defined below are specific to the
+BCM6328-style timer:
+
+- offset: Should be 0x34 to denote the offset of the TIMER_WD_TIMER_RESET register
+  from the beginning of the TIMER block
+- mask: Should be 1 for the SoftRst bit.
+
+Example:
+
+       timer: timer@80 {
+               compatible = "brcm,bcm6328-timer", "syscon";
+               reg = <0x80 0x3c>;
+       };
+
+       reboot {
+               compatible = "syscon-reboot";
+               regmap = <&timer>;
+               offset = <0x34>;
+               mask = <0x1>;
+       };
