    1 NVIDIA Tegra30 timer
    2 
    3 The Tegra30 timer provides ten 29-bit timer channels, a single 32-bit free
    4 running counter, and 5 watchdog modules. The first two channels may also
    5 trigger a legacy watchdog reset.
    6 
    7 Required properties:
    8 
    9 - compatible : For Tegra30, must contain "nvidia,tegra30-timer".  Otherwise,
   10   must contain '"nvidia,<chip>-timer", "nvidia,tegra30-timer"' where
   11   <chip> is tegra124 or tegra132.
   12 - reg : Specifies base physical address and size of the registers.
   13 - interrupts : A list of 6 interrupts; one per each of timer channels 1
   14     through 5, and one for the shared interrupt for the remaining channels.
   15 - clocks : Must contain one entry, for the module clock.
   16   See ../clocks/clock-bindings.txt for details.
   17 
   18 timer {
   19         compatible = "nvidia,tegra30-timer", "nvidia,tegra20-timer";
   20         reg = <0x60005000 0x400>;
   21         interrupts = <0 0 0x04
   22                       0 1 0x04
   23                       0 41 0x04
   24                       0 42 0x04
   25                       0 121 0x04
   26                       0 122 0x04>;
   27         clocks = <&tegra_car 214>;
