AOP (Always-On-Processor) DDR Related Messaging



The AOP DDR messaging driver is used to send messages to the AOP,

using the mailbox interface, to lower the DDR frequency during reboot.



Required properties



- compatible : "qcom,aop-ddr-msgs"

- mbox : QMP mailbox phandle and channel identifier



Optional properties:

-mbox-name: name of the mailbox



Example:

	qcom,aop-ddr-msgs {

		compatible = "qcom,aop-ddr-msgs";

		mboxes = <&qmp_aop 0>;

	};
