+title: ST-Ericsson DB8500 PRCMU - Power Reset and Control Management Unit
+
+maintainers:
+ - Linus Walleij <linus.walleij@linaro.org>
+
+description:
+ The DB8500 Power Reset and Control Management Unit is an XP70 8-bit
+ microprocessor that is embedded in the always-on power domain of the
+ DB8500 SoCs to manage the low power states, powering up and down parts
+ of the silicon, and controlling reset of different IP blocks.

+ compatible:
+ description: The device is compatible both to the device-specific
+ compatible "stericsson,db8500-prcmu" and "syscon". The latter
+ compatible is needed for the device to be exposed as a system
+ controller so that arbitrary registers can be access by
+ different operating system components.
