2018-05-23rtc: st-lpc: fix possible race conditionAlexandre Belloni1-15/+9
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.

2018-03-27rtc: st-lpc: remove artificial limitationAlexandre Belloni1-16/+0
The LPC RTC supports dates way beyond 2038, don't limit it artificially as the kernel handles dates after 2038 properly. Signed-off-by: Alexandre Belloni <[email protected]>
2017-07-09rtc: st-lpc: make it robust against y2038/2106 bugBenjamin Gaignard1-11/+8

2015-07-23rtc: st: Update IP layout information to include ClocksourceLee Jones1-1/+1
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.

2015-04-30rtc: st: Add new driver for ST's LPC RTCLee Jones1-0/+354
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. Cc: Alessandro Zummo <[email protected]> Signed-off-by: Lee Jones <[email protected]>
