AOP (Always-On-Processor) DDRSS Commands



The AOP DDRSS commands driver is used to send commands

to the AOP, using the mailbox interface, to affect the

behavior of the DDR.



Required properties



- compatible : "qcom,aop-ddrss-cmds"

- mbox : QMP mailbox phandle and channel identifier



Optional properties:

-mbox-name: name of the mailbox



Example:

	qcom,aop-ddrss-cmds {

		compatible = "qcom,aop-ddrss-cmds";

		mboxes = <&qmp_aop 0>;

	};
