Merge tag 'rtc-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux
Pull RTC updates from Alexandre Belloni:
"It is now possible to add custom sysfs attributes while avoiding a
possible race condition. Unused code has been removed resulting in a
nice reduction of the code base. And more drivers have been switched
to SPDX by their maintainers.
Summary:
Subsystem:
- new helpers to add custom sysfs attributes
- struct rtc_task removal along with rtc_irq_[un]register()
- rtc_irq_set_state and rtc_irq_set_freq are not exported anymore
Drivers:
- armada38x: reset after rtc power loss
- ds1307: now supports m41t11
- isl1208: now supports isl1219 and tamper detection
- pcf2127: internal SRAM support"
