+description: |+
+ MStar, SigmaStar and Mediatek TV SoCs contain multiple legacy
+ interrupt controllers that routes interrupts to the GIC.
+
+ The HW block exposes a number of interrupt controllers, each
+ can support up to 64 interrupts.
+
+properties:
+ compatible:
+ const: mstar,mst-intc
+
+ interrupt-controller: true
+
+ "#interrupt-cells":
+ const: 3
+ description: |
+ Use the same format as specified by GIC in arm,gic.yaml.
+
+ reg:
+ maxItems: 1
+
+ mstar,irqs-map-range:
+ description: |
+ The range <start, end> of parent interrupt controller's interrupt
+ lines that are hardwired to mstar interrupt controller.
+ $ref: /schemas/types.yaml#/definitions/uint32-matrix
+ items:
+ minItems: 2
+ maxItems: 2
+
+ mstar,intc-no-eoi:
+ description:
+ Mark this controller has no End Of Interrupt(EOI) implementation.
