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. 16 17Example: 18 19timer { 20 compatible = "nvidia,tegra20-rtc"; 21 reg = <0x7000e000 0x100>; 22 interrupts = <0 2 0x04>; 23 clocks = <&tegra_car 4>; 24}; 25
