Since commit 43a7206b ("driver core: class: make class_register() take a const *"), the driver core allows for struct class to be in read-only memory, so move the rtc_class structure to be declared at build time placing it into read-only memory, instead of having to be dynamically allocated at boot time.

The abracon,tc-diode and abracon,tc-resistor DT properties are only valid for the ABx0804 and ABx0805. Furthermore, they must both be present, or neither of them must be specified. Add rules to check this. The generic abracon,abx08x compatible string doesn't indicate which chip variant is used, but performs auto-detection at runtime. It must this also allow the two above properties. Signed-off-by:

Commit e8c04985 ("dt-bindings: rtc: convert MT2717 RTC to the json-schema") and commit aef3952e ("dt-bindings: rtc: convert MT7622 RTC to the json-schema") convert rtc-mt{2712,7622}.txt to mediatek,mt{2712,7622}-rtc.yaml, but misses to adjust the file entries in MAINTAINERS. Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a broken reference. Repair these file entries in ARM/Mediatek RTC DRIVER. Signed-off-by:

Fix the register value comparison in the `max31335_volatile_reg` function for the interrupt status register. MAX31335_STATUS1 macro definition corresponds to the actual interrupt status register. Fixes: dedaf03b ("rtc: max31335: add driver support") Signed-off-by:

IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set it directly thru "make *config", so drivers should select it instead of depending on it if they need it. Relying on it being set for a dependency is risky. Consistently using "select" or "depends on" can also help reduce Kconfig circular dependency issues. Therefore, change the use of "depends on" for IRQ_DOMAIN to "select" for RTC_DRV_MT6397.

ds1511_rtc_read_alarm was useless as it is only called at boot time so the alarm members of pdata have not yet been set. Read the actual registers so there is a chance to get a meaningful value. Then, drop the alarm related members of pdata as they are not used anymore. Link: https://lore.kernel.org/r/20240227230431.1837717-10-alexandre.belloni@bootlin.comSigned-off-by:

ds1511_rtc_update_alarm is called twice but one of the call is overkill as it only has to enable or disable the alarm instead of updating all the alarm registers. Merge it in its main call site and introduce a new finction to enable or disable the alarm. Link: https://lore.kernel.org/r/20240227230431.1837717-7-alexandre.belloni@bootlin.comSigned-off-by:
