-* sun6i Real Time Clock
-
-RTC controller for the Allwinner A31
-
-Required properties:
-- compatible : Should be one of the following combinations:
- - "allwinner,sun6i-a31-rtc"
- - "allwinner,sun8i-a23-rtc"
- - "allwinner,sun8i-h3-rtc"
- - "allwinner,sun8i-r40-rtc", "allwinner,sun8i-h3-rtc"
- - "allwinner,sun8i-v3-rtc"
- - "allwinner,sun50i-a64-rtc", "allwinner,sun8i-h3-rtc"
- - "allwinner,sun50i-h5-rtc"
-
- Where there are two or more compatible strings, this
- denotes the hardware covered by the most specific one
- is backward-compatible with the latter ones, and the
- implementation for the latter ones can be used, albeit
- with reduced functionality.
-
-- reg : physical base address of the controller and length of
- memory mapped region.
-- interrupts : IRQ lines for the RTC alarm 0 and alarm 1, in that order.
-
-Required properties for new device trees
-- clocks : phandle to the 32kHz external oscillator
-- clock-output-names : names of up to three clock outputs. See below.
-- #clock-cells : must be equal to 1.
-
-The RTC provides the following clocks at the given indices:
-- 0: LOSC
-- 1: LOSC external output, known as X32KFOUT in the datasheet.
- This clock is not available on the A31 and is deprecated for old
- device trees still using the "allwinner,sun6i-a31-rtc" compatible.
-- 2: InternalOSC, or internal RC oscillator (A64/H3/H5 only)
-
-Example:
-
-rtc: rtc@1f00000 {
- compatible = "allwinner,sun6i-a31-rtc";
- reg = <0x01f00000 0x400>;
- interrupts = <0 40 4>, <0 41 4>;
- clock-output-names = "osc32k";
- clocks = <&ext_osc32k>;
- #clock-cells = <1>;
-};
