Cadence Real Time Clock
|
|
|
|
The Cadence RTC controller with date, time and alarm capabilities.
|
|
The alarm may wake the system from low-power state.
|
|
|
|
Required properties:
|
|
- compatible: Should be "cdns,rtc-r109v3"
|
|
- reg: Specifies base physical address and size of the register area.
|
|
- interrupts: A single interrupt specifier.
|
|
- clocks: Must contain two entries:
|
|
- pclk: APB registers clock
|
|
- ref_clk: reference 1Hz or 100Hz clock, depending on IP configuration
|
|
See ../clocks/clock-bindings.txt for details.
|
|
|
|
Example:
|
|
rtc0: rtc@fd080000 {
|
|
compatible = "cdns,rtc-r109v3";
|
|
reg = <0xfd080000 0x1000>;
|
|
|
|
clock-names = "pclk", "ref_clk";
|
|
clocks = <&sysclock>, <&refclock>;
|
|
|
|
interrupt-parent = <&gic>;
|
|
interrupts = <0 6 IRQ_TYPE_LEVEL_HIGH>;
|
|
};
