ARM: dts: msm: Add virtual subsystem notification nodes for SA8155 VM

Subsystem Notification Virtual Driver

The guest VM uses this driver to communicate

subsystem state notifications to a backend driver

via the virtual device's registers.

[Root level node]

Required Properties:

-compatible : Should be "qcom,subsys-notif-virt"

-reg : The start and size of the virtual device's

	register set.

-reg-names :  Should be "vdev_base" for virtual device's

	base address.

[Child nodes]

-subsys-names : The name of the subsystem that the

	driver is registering to notifications for.

-offset : The offset from the virtual device's register

	base where the subsystem state will be written.

-type : The type of the subsystem.

	"virtual" - When the subsystem is loaded by the host VM.

	"native" - When the subsystem is loaded by the guest VM.

Required Property for "virtual" subsystem types:

-interrupts : Tuple defining the interrupt which the driver must

		register for to receive subsystem state notifications

		from the backend.

-interrupt-names: Must be "state-irq"

Example:

	subsys_notif_virt: qcom,subsys_notif_virt@2D000000 {

		compatible = "qcom,subsys-notif-virt";

		reg = <0x2D000000 0x400>;

		reg-names = "vdev_base";

		adsp {

			subsys-name = "adsp";

			interrupts = <GIC_SPI 43 IRQ_TYPE_LEVEL_HIGH>;

			interrupt-names = "state-irq";

			type = "virtual";

			offset = <0>;

		};

		modem {

			subsys-name = "modem";

			type = "native";

			offset = <256>;

		};

	};

		qcom,qsee-reentrancy-support = <2>;

	};

	subsys_notif_virt: qcom,subsys_notif_virt@2D000000 {

		compatible = "qcom,subsys-notif-virt";

		reg = <0x2D000000 0x400>;

		reg-names = "vdev_base";

		adsp {

			subsys-name = "adsp";

			interrupts = <GIC_SPI 43 IRQ_TYPE_LEVEL_HIGH>;

			interrupt-names = "state-irq";

			type = "virtual";

			offset = <0>;

		};

		wlan {

			subsys-name = "wlan";

			type = "native";

			offset = <512>;

		};

	};

};
