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. | |

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. | |
