1* sun6i Real Time Clock 2 3RTC controller for the Allwinner A31 4 5Required properties: 6- compatible : Should be "allwinner,sun6i-a31-rtc" 7- reg : physical base address of the controller and length of 8 memory mapped region. 9- interrupts : IRQ lines for the RTC alarm 0 and alarm 1, in that order. 10 11Required properties for new device trees 12- clocks : phandle to the 32kHz external oscillator 13- clock-output-names : names of the LOSC and its external output clocks created 14- #clock-cells : must be equals to 1. The RTC provides two clocks: the 15 LOSC and its external output, with index 0 and 1 16 respectively. 17 18Example: 19 20rtc: rtc@1f00000 { 21 compatible = "allwinner,sun6i-a31-rtc"; 22 reg = <0x01f00000 0x54>; 23 interrupts = <0 40 4>, <0 41 4>; 24 clock-output-names = "osc32k", "osc32k-out"; 25 clocks = <&ext_osc32k>; 26 #clock-cells = <1>; 27}; 28
