Add device binding documentation for Qualcomm Technologies, Inc. (QTI)
SoC sleep stats driver. The driver is used for displaying SoC sleep
statistic maintained by Always On Processor or Resource Power Manager.

+description:
+ Always On Processor/Resource Power Manager maintains statistics of the SoC
+ sleep modes involving powering down of the rails and oscillator clock.
+
+ Statistics includes SoC sleep mode type, number of times low power mode were
+ entered, time of last entry, time of last exit and accumulated sleep duration.
+
+properties:
+ compatible:
+ enum:
+ - qcom,rpmh-sleep-stats
+ - qcom,rpm-sleep-stats
+
+ reg:
+ maxItems: 1
+
+required:
+ - compatible
+ - reg
+
+examples:
+ # Example of rpmh sleep stats
+ - |
+ rpmh-sleep-stats@c3f0000 {
+ compatible = "qcom,rpmh-sleep-stats";
+ reg = <0 0x0c3f0000 0 0x400>;
The example is built with #address-cells = <1> and #size-cells = <1>, so
this needs to be reg = <0x0c3f0000 0x400>.

Bjorn

Thanks, Fixed in v7.

Thanks,
