Alexandre Belloni d2bc4cece1 rtc: st-lpc: remove unnecessary check
The RTC core already ensures the alarm is set to a time in the future, it
is not necessary to check again in the driver.

Alexandre Belloni d482510fee rtc: st-lpc: fix possible race condition
The IRQ is requested before the struct rtc is allocated and registered, but
this struct is used in the IRQ handler. This may lead to a NULL pointer
dereference.

Switch to devm_rtc_allocate_device/rtc_register_device to allocate the rtc
before requesting the IRQ.

the kernel handles dates after 2038 properly.

Lee Jones 742e40978f rtc: st: Update IP layout information to include Clocksource
Initial submission adding support for this IP only included Watchdog and
the Real-Time Clock.  Now the third (and final) device is enabled this
trivial patch is required to update the comment in the RTC driver to
encompass Clocksource.

Lee Jones b5b2bdfc28 rtc: st: Add new driver for ST's LPC RTC
ST's Low Power Controller (LPC) controls two devices; watchdog and RTC.
Only one of the devices can be used at any one time.  This is enforced
by the correlating MFD driver.  This portion of the driver-set controls
the Real Time Clock.
