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