1*c66ec88fSEmmanuel VadotNVIDIA Tegra20 real-time clock 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotThe Tegra RTC maintains seconds and milliseconds counters, and five alarm 4*c66ec88fSEmmanuel Vadotregisters. The alarms and other interrupts may wake the system from low-power 5*c66ec88fSEmmanuel Vadotstate. 6*c66ec88fSEmmanuel Vadot 7*c66ec88fSEmmanuel VadotRequired properties: 8*c66ec88fSEmmanuel Vadot 9*c66ec88fSEmmanuel Vadot- compatible : For Tegra20, must contain "nvidia,tegra20-rtc". Otherwise, 10*c66ec88fSEmmanuel Vadot must contain '"nvidia,<chip>-rtc", "nvidia,tegra20-rtc"', where <chip> 11*c66ec88fSEmmanuel Vadot can be tegra30, tegra114, tegra124, or tegra132. 12*c66ec88fSEmmanuel Vadot- reg : Specifies base physical address and size of the registers. 13*c66ec88fSEmmanuel Vadot- interrupts : A single interrupt specifier. 14*c66ec88fSEmmanuel Vadot- clocks : Must contain one entry, for the module clock. 15*c66ec88fSEmmanuel Vadot See ../clocks/clock-bindings.txt for details. 16*c66ec88fSEmmanuel Vadot 17*c66ec88fSEmmanuel VadotExample: 18*c66ec88fSEmmanuel Vadot 19*c66ec88fSEmmanuel Vadottimer { 20*c66ec88fSEmmanuel Vadot compatible = "nvidia,tegra20-rtc"; 21*c66ec88fSEmmanuel Vadot reg = <0x7000e000 0x100>; 22*c66ec88fSEmmanuel Vadot interrupts = <0 2 0x04>; 23*c66ec88fSEmmanuel Vadot clocks = <&tegra_car 4>; 24*c66ec88fSEmmanuel Vadot}; 25
