module: Convert symbol namespace to string literal

2024-12-02T19:34:44Z

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

rtc: ab-eoz9: don't fail temperature reads on undervoltage notification

2024-11-25T22:34:12Z

The undervoltage flags reported by the RTC are useful to know if the time and date are reliable after a reboot. Although the threshold VLOW1 indicates that the thermometer has been shutdown and time compensation is off, it doesn't mean that the temperature readout is currently impossible. As the system is running, the RTC voltage is now fully established and we can read the temperature.

rtc: rzn1: reduce register access

2024-11-25T22:32:50Z

This RTC has special 32bit registers which return multiple of the same 8bit registers at once. Use these to minimize register access. Also, do the to/from BCD conversions right away, so 'tm' always contains values as described in time.h.

rtc: rzn1: drop superfluous wday calculation

2024-11-25T22:32:50Z

The week register simply counts from 0 to 6 where the numbers do not even represent a specific weekday. So we can adopt 'tm_wday' numbering of the RTC core without converting it.

rtc: ab-eoz9: fix abeoz9_rtc_read_alarm

2024-11-18T11:14:37Z

abeoz9_rtc_read_alarm assumes we always read the alarm in 12-hour mode while abeoz9_rtc_set_alarm will always set it in 24-hour mode. We could support 12-hour mode in both functions but it seems very unlikely that the RTC would be set to 12-hour mode now as the driver has been setting it to 24-hour mode for a while now. The setting is undefined at power-up and unchanged by subsequent resets which doesn't help us.
