a29de86521 rtc: imx-sc: Align imx sc msg structs to 4
The imx SC api strongly assumes that messages are composed out of
4-bytes words but some of our message structs have odd sizeofs.

This produces many oopses with CONFIG_KASAN=y.

Fix by marking with __aligned(4).

5840748520 rtc: jz4740: Add support for JZ4760 SoC
The WENR feature (set a magic value to enable RTC registers read-write)
first appeared on the JZ4760; the JZ4780 came much later.

Since it would be dangerous to specify a newer SoC's compatible string as
the fallback of an older SoC's compatible string, we add support for the
"ingenic,jz4760-rtc" compatible string in the driver.

This will permit to support the JZ4770 by having:
compatible = "ingenic,jz4770-rtc", "ingenic,jz4760-rtc";

Instead of doing:
compatible = "ingenic,jz4770-rtc", "ingenic,jz4780-rtc";

ec98a87509 rtc: sun6i: Make external 32k oscillator optional
Some boards, like OrangePi PC2 (H5), OrangePi Plus 2E (H3) and Tanix TX6
(H6) don't have external 32kHz oscillator. Till H6, it didn't really
matter if external oscillator was enabled because HW detected error and
fall back to internal one. H6 has same functionality but it's the first
SoC which have "auto switch bypass" bit documented and always enabled in
driver. This prevents RTC to work correctly if external crystal is not
present on board. There are other side effects - all peripherals which
depends on this clock also don't work (HDMI CEC for example).

Make clocks property optional. If it is present, select external
oscillator. If not, stay on internal.
