| 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>; | |
| }; |
