QTI Virtio SPMI controller (Virtio PMIC Arbiter)
|
||
|
|
|
||
|
|
The Virtio SPMI PMIC Arbiter is a frontend proxy based on backend virtio device.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : should be "qcom,viospmi-pmic-arb".
|
||
|
|
- #address-cells : must be set to 2
|
||
|
|
- #size-cells : must be set to 0
|
||
|
|
- interrupt-controller : boolean indicator that the PMIC arbiter is an interrupt controller
|
||
|
|
- #interrupt-cells : must be set to 4. Interrupts are specified as a 4-tuple:
|
||
|
|
cell 1: slave ID for the requested interrupt (0-15)
|
||
|
|
cell 2: peripheral ID for requested interrupt (0-255)
|
||
|
|
cell 3: the requested peripheral interrupt (0-7)
|
||
|
|
cell 4: interrupt flags indicating level-sense information, as defined in
|
||
|
|
dt-bindings/interrupt-controller/irq.h
|
||
|
|
|
||
|
|
Example Virtio PMIC-Arbiter:
|
||
|
|
|
||
|
|
spmi_bus: qcom,spmi {
|
||
|
|
compatible = "qcom,viospmi-pmic-arb";
|
||
|
|
interrupt-names = "periph_irq";
|
||
|
|
interrupts = <GIC_SPI 481 IRQ_TYPE_NONE>;
|
||
|
|
qcom,ee = <0>;
|
||
|
|
#address-cells = <2>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
interrupt-controller;
|
||
|
|
#interrupt-cells = <4>;
|
||
|
|
cell-index = <0>;
|
||
|
|
};
|
||
|
|
|
||
|
|
viospmi: virtio-spmi@c440000 {
|
||
|
|
compatible = "virtio,mmio";
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <1>;
|
||
|
|
reg = <0xc440000 0x1100>;
|
||
|
|
interrupts = <GIC_SPI 100 IRQ_TYPE_NONE>;
|
||
|
|
status = "okay";

};
