1NVIDIA Tegra20 real-time clock
2
3The Tegra RTC maintains seconds and milliseconds counters, and five alarm
4registers. The alarms and other interrupts may wake the system from low-power
5state.
6
7Required 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.

19timer {
20	compatible = "nvidia,tegra20-rtc";
21	reg = <0x7000e000 0x100>;
22	interrupts = <0 2 0x04>;
23	clocks = <&tegra_car 4>;
24};
