| 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 : should be "nvidia,tegra20-rtc". |
| 10 | - reg : Specifies base physical address and size of the registers. |
| 11 | - interrupts : A single interrupt specifier. |
| Stephen Warren | d8f6479 | 2013-11-06 14:00:25 -0700 | [diff] [blame] | 12 | - clocks : Must contain one entry, for the module clock. |
| 13 | See ../clocks/clock-bindings.txt for details. |
