BSM or Backup Switch Mode is a common feature on RTCs, allowing to select how the RTC will decide when to switch from its primary power supply to the backup power supply. It is necessary to be able to set it from userspace as there are uses cases where it has to be done dynamically.

Supported values are: RTC_BSM_DISABLED: disabled RTC_BSM_DIRECT: switching will happen as soon as Vbackup > Vdd RTC_BSM_LEVEL: switching will happen around a threshold, usually with an hysteresis RTC_BSM_STANDBY: switching will not happen until Vdd > Vbackup, this is useful to ensure the RTC doesn't draw any power until the device is first powered on.

rtc: expose correction feature

Add a new feature for RTCs able to correct the oscillator imprecision. This is also called offset or trimming. Such drivers have a .set_offset callback, use that to set the feature bit from the core.

[DRIVER] rv3028: add support for setting BSM mode in device tree

This commit adds the devicetree node "backup-switch-mode" to the rv3028 driver. It supports the following values:

direct
level
disabled

The values correspond to the different BSM options in the datasheet. When the setting is present in the devicetree, the driver checks the current mode during the probing phase. If the desired value differs from the current value, it is written to the RTC and a message is printed to dmesg, stating the new mode.

rtc: rv3028: Fix codestyle errors

Compiler warnings：

drivers/rtc/rtc-rv3028.c: In function 'rv3028_param_set': drivers/rtc/rtc-rv3028.c:559:20: warning: statement will never be executed [-Wswitch-unreachable] 559 | u8 mode; | ^~~~ drivers/rtc/rtc-rv3028.c: In function 'rv3028_param_get': drivers/rtc/rtc-rv3028.c:526:21: warning: statement will never be executed [-Wswitch-unreachable] 526 | u32 value; | ^~~~~

Fix it by moving the variable declaration to the beginning of the function.

rtc: rv3028: add BSM support

Backup Switch Mode controls how the RTC decides when to switch to the backup power supply. As it is disabled by default, provide a way to enable and configure it.
