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>;
};
};
