Add device tree binding for the BCM6345 timer. This is required for the
BCM6345 watchdog which needs to respond to one of the timer interrupts.

+Broadcom BCM6345 Timer
+
+This block is a timer that is connected to one interrupt on the main interrupt
+controller and functions as a programmable interrupt controller for timer events.
+
+- 3 to 4 independent timers with their own maskable level interrupt bit (but not
+ per CPU because there is only one parent interrupt and the timers share it)
+
+- 1 watchdog timer with an unmaskable level interrupt
+
+- Contains one enable/status word pair
+
+- No atomic set/clear operations
+
+The lack of per CPU ability of timers makes them unusable as a set of
+clockevent devices, otherwise they could be attached to the remaining
+interrupts.
+
+The BCM6318 also has a separate interrupt for every timer except the watchdog.
+
+Required properties:
+
+- compatible: should be "brcm,bcm<soc>-timer", "brcm,bcm6345-timer"
+- reg: specifies the base physical address and size of the registers, excluding
+ the watchdog registers
+- interrupt-controller: identifies the node as an interrupt controller
+- #interrupt-cells: specifies the number of cells needed to encode an interrupt
+ source, should be 1.
+- interrupt-parent: specifies the phandle to the parent interrupt controller(s)
+ this one is cascaded from
+- interrupts: specifies the interrupt line(s) in the interrupt-parent controller
+ node for the main timer interrupt, followed by the individual timer interrupts
+ if present; valid values depend on the type of parent interrupt controller
+
+Example:
+
+timer: timer@0x10000080 {
+ compatible = "brcm,bcm63168-timer", "brcm,bcm6345-timer";
+ reg = <0x10000080 0x1c>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ interrupt-parent = <&periph_intc>;
+ interrupts = <0>;
+};
+
+timer: timer@0x10000040 {
+ compatible = "brcm,bcm6318-timer", "brcm,bcm6345-timer";
+ reg = <0x10000040 0x28>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ interrupt-parent = <&periph_intc>;
+ interrupts = <31>, <0>, <1>, <2>, <3>;
+};
