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" * tag 'rtc-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: (34 commits) rtc: ds1307: simplify hwmon config rtc: s5m: Add SPDX license identifier rtc: maxim: Add SPDX license identifiers rtc: isl1219: add device tree documentation rtc: isl1208: set ev-evienb bit from device tree rtc: isl1208: Add "evdet" interrupt source for isl1219 rtc: isl1208: add support for isl1219 with tamper detection rtc: sysfs: facilitate attribute add to rtc device rtc: remove struct rtc_task char: rtc: remove task handling rtc: pcf85063: preserve control register value between stop and start rtc: sh: remove unused variable rtc_dev rtc: unexport rtc_irq_set_* rtc: simplify rtc_irq_set_state/rtc_irq_set_freq rtc: remove irq_task and irq_task_lock rtc: remove rtc_irq_register/rtc_irq_unregister rtc: sh: remove dead code rtc: sa1100: don't set PIE frequency rtc: ds1307: support m41t11 variant rtc: ds1307: fix data pointer to m41t0 ...
