[GIT,PULL] RTC for 4.19

Hi Linus,

Here is the pull-request for the RTC subsystem for 4.19.

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.

The following changes since commit ce397d215ccd07b8ae3f71db689aedb85d56ab40:

  Linux 4.18-rc1 (2018-06-17 08:04:49 +0900)

  rtc: ds1307: simplify hwmon config (2018-08-16 07:46:41 +0200)

----------------------------------------------------------------
RTC for 4.19

Subsystem:
 - new helpers to add custom sysfs attributes
 - struct rtc_task removal along with rtc_irq_register/rtc_irq_unregister
 - 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

You can still find stale mentions of it by grepping for it:

 * @task: currently registered with rtc_irq_register()

which should presumably be fixed up too.

That's not holding me from doing the pull, but I thought I'd mention it.

Ah right, I'll clean that up along with another suggestion from Arnd.
