    1 NVIDIA Tegra20 real-time clock
    2 
    3 The Tegra RTC maintains seconds and milliseconds counters, and five alarm
    4 registers. The alarms and other interrupts may wake the system from low-power
    5 state.
    6 
    7 Required properties:
    8 
    9 - compatible : For Tegra20, must contain "nvidia,tegra20-rtc".  Otherwise,
   10   must contain '"nvidia,<chip>-rtc", "nvidia,tegra20-rtc"', where <chip>
   11   can be tegra30, tegra114, tegra124, or tegra132.
   12 - reg : Specifies base physical address and size of the registers.
   13 - interrupts : A single interrupt specifier.
   14 - clocks : Must contain one entry, for the module clock.
   15   See ../clocks/clock-bindings.txt for details.
   16 
   17 Example:
   18 
   19 timer {
   20         compatible = "nvidia,tegra20-rtc";
   21         reg = <0x7000e000 0x100>;
   22         interrupts = <0 2 0x04>;
   23         clocks = <&tegra_car 4>;
   24 };
