     * MSM Timer
     
     Properties:
     
     - compatible : Should at least contain "qcom,msm-timer". More specific
                    properties specify which subsystem the timers are paired with.
     
                    "qcom,kpss-timer" - krait subsystem
                    "qcom,scss-timer" - scorpion subsystem
    
    - interrupts : Interrupts for the debug timer, the first general purpose
                   timer, and optionally a second general purpose timer, and
                   optionally as well, 2 watchdog interrupts, in that order.
    
    - reg : Specifies the base address of the timer registers.
    
    - clocks: Reference to the parent clocks, one per output clock. The parents
              must appear in the same order as the clock names.
    
    - clock-names: The name of the clocks as free-form strings. They should be in
                   the same order as the clocks.
    
    - clock-frequency : The frequency of the debug timer and the general purpose
                        timer(s) in Hz in that order.
    
    Optional:
    
    - cpu-offset : per-cpu offset used when the timer is accessed without the
                   CPU remapping facilities. The offset is
                   cpu-offset + (0x10000 * cpu-nr).
    
    Example:
    
           timer@200a000 {
                   compatible = "qcom,scss-timer", "qcom,msm-timer";
                   interrupts = <1 1 0x301>,
                                <1 2 0x301>,
                                <1 3 0x301>,
                                <1 4 0x301>,
                                <1 5 0x301>;
                   reg = <0x0200a000 0x100>;
                   clock-frequency = <19200000>,
                                     <32768>;
                   clocks = <&sleep_clk>;
                   clock-names = "sleep";
                   cpu-offset = <0x40000>;
           };
