[0/5] rtc: ingenic: various updates

Message

Hi,

Here's a set of patches for the Ingenic RTC driver (jz4740-rtc).

Patch [1/5] and [4/5] update the DT binding documentation and update the
driver to support the CLK32K pin. This pin optionally supplies a 32 kHz
clock, which is required on the MIPS CI20 board for the WiFi/Bluetooth
chip to work.

Patch [2/5] is a code cleanup. Patch [3/5] fixes the RTC time yielding
an impossible value after a power loss.

Finally, patch [5/5] is *RFC*. I do not know if it works, as I have
absolutely no idea about how to test it.

Cheers,
-Paul
