Chen-Yu Tsai 9765d2d943 rtc: sun6i: Add sun6i RTC driver
This patch introduces the driver for the RTC in the Allwinner A31 and
A23 SoCs.

Unlike the RTC found in A10/A20 SoCs, which was part of the timer, the
RTC in A31/A23 are a separate hardware block, which also contain a few
controls for the RTC block hardware (a regulator and RTC block GPIO pin
latches), while also having separate interrupts for the alarms.

The hardware is different enough to make a different driver for it.

* sun6i Real Time Clock
RTC controller for the Allwinner A31
Required properties:
- compatible : Should be "allwinner,sun6i-a31-rtc"
- 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.
Example:
rtc: rtc@01f00000 {
compatible = "allwinner,sun6i-a31-rtc";
reg = <0x01f00000 0x54>;
interrupts = <0 40 4>, <0 41 4>;
};
