[PATCH v2 0/5] rtc: Enhance RTC driver with BBPU bit definitions and shutdown handling

[ot_shunxi.zhang at mediatek.com]

From: Shunxi Zhang <ot_shunxi.zhang at mediatek.com>

(1) Add new bits definitions for RTC_BBPU register.
(2) Add new functions to reset the BBPU alarm status in mt6397 RTC driver
(3) Add mtk_rtc_shutdown function to handle RTC shutdown events.
(4) For the V1 version comments, the following modifications are made: 
(4.1)the formatting changes are separated into a distinct patch. 
(4.2)Since the rtc-mt6397.c file is a fusion of multiple RTC drivers 
for the mt6358, mt6359, and mt6357 RTCs, the definitions of certain bits 
in the RTC_BBPU register differ among these RTCs. The mt6359 supports 
the alarm status bit, while both mt6358 and mt6357 do not. Therefore, 
the alarm-sta-supported property is added in the mt6359.dtsi file to 
differentiate between the different RTCs. 
(4.3)Additionally, the operation to disable IRQ in the shutdown function 
is removed.
