2017-01-17power: reset: at91-poweroff: timely shutdown LPDDR memoriesAlexandre Belloni1-1/+48
LPDDR memories can only handle up to 400 uncontrolled power off. Ensure the proper power off sequence is used before shutting down the platform.

2016-04-10power: reset: at91-shdwc: add new shutdown controller driverNicolas Ferre1-0/+282
Sama5d2 SoC has a completely new shutdown controller with new features and register layout. It thus makes sense to add a new driver for this new peripheral. This driver is Device Tree only and handles events from the wake-up pin and the RTC. As the register layout may change in the future, so some values are encoded in a configuration structure.
