Subject[PATCH v2 0/4] rtc: mediatek: add support for SoC based RTC on MT7622
From: Sean Wang <>

Changes since v1:
- Rename to rtc-mt7622.c from rtc-mediatek.c
- Use [readl,writel]_relaxed instead of __raw_* version
- Remove redundant register reading in mtk_rtc_get_alarm_or_time()
- Stop alarm when alarm is really expired in mtk_rtc_alarmirq()
- Extend the maximum year the RTC/Alarm can count/support using year rebasing
- Remove unnesscary log which is already done in core layer

This patchset introduces support for MediaTek SoC based real time clock
(RTC) Currently, the driver is already tested successfully with hwclock
and wakealarm on MT7622 SoC. And it should also be workable on other
similar MediaTek SoCs. And patch 3 is a distinct patch used to distinguish
between either SoC based or PMIC based RTC to avoid confusion for the RTC
selection for the target SoC.

dt-bindings: rtc: mediatek: add bindings for MediaTek SoC based RTC
rtc: mediatek: add driver for RTC on MT7622 SoC
rtc: mediatek: enhance the description for MediaTek PMIC based RTC
rtc: mediatek: update MAINTAINERS entry with MediaTek RTC driver
