rtc: s5m: Drop S5M8763 support

2023-04-26T10:40:26Z

The S5M8763 MFD has no device tree compatible, and since board file support for it was removed, there's no way to use this MFD. After removing the remaining code for it from the MFD driver, also remove support for it in the s5m RTC driver, and all remaining references to it.

rtc: s5m: drop unneeded MODULE_ALIAS

2021-09-25T21:26:37Z

The MODULE_DEVICE_TABLE already creates proper alias for platform driver. Having another MODULE_ALIAS causes the alias to be duplicated. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20210916164604.134924-1-krzysztof.kozlowski@canonical.com

rtc: s5m: enable wakeup only when available

2021-08-06T08:31:59Z

Call device_init_wakeup() only when alarms are available and the RTC is actually able to wake up the system. Signed-off-by: Alexandre Belloni Reviewed-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20210804104133.5158-3-alexandre.belloni@bootlin.com

rtc: s5m: signal the core when alarm are not available

2021-08-06T08:31:59Z

Clear the RTC_FEATURE_ALARM bit to signal to the core when alarms are not available to ensure the alarm callbacks are never called and userspace is aware alarms are not supported.

rtc: s5m: Check return value of s5m_check_peding_alarm_interrupt()

2021-07-10T00:41:52Z

s5m_check_peding_alarm_interrupt() in s5m_rtc_read_alarm() gets the return value, but doesn't use it. This modifies using the s5m_check_peding_alarm_interrupt()"s return value as the s5m_rtc_read_alarm()'s return value.

rtc: s5m: Remove reference to parent's device pdata

2021-04-29T21:37:18Z

The S5M RTC driver does not use parent's device (sec-core PMIC driver) platform data so there is no need to check for it. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/20210420170244.13467-3-krzysztof.kozlowski@canonical.com
