MediaTek PMIC based RTC is an independent function of MediaTek PMIC that works
as a type of multi-function device (MFD). The RTC can be configured and set up
with PMIC wrapper bus which is a common resource shared with the other
functions found on the same PMIC.
For MediaTek PMIC MFD bindings, see:

For MediaTek PMIC wrapper bus bindings, see:
../soc/mediatek/pwrap.txt
Required properties:
- compatible: Should be one of follows
"mediatek,mt6323-rtc": for MT6323 PMIC
"mediatek,mt6358-rtc": for MT6358 PMIC
"mediatek,mt6366-rtc", "mediatek,mt6358-rtc": for MT6366 PMIC
"mediatek,mt6397-rtc": for MT6397 PMIC
Example:
pmic {
compatible = "mediatek,mt6323";
...
rtc {
