[PATCH 1/2] dt-bindings: interrupt-controller: aspeed,ast2400-vic: Convert to DT schema

Andrew Jeffery
2024-08-02T05:36:50Z

Squash warnings such as:

arch/arm/boot/dts/aspeed/aspeed-bmc-facebook-galaxy100.dtb: /ahb/interrupt-controller@1e6c0080: failed to match any schema with compatible: ['aspeed,ast2400-vic']

The YAML DT schema defines an optional property, valid-sources, which
was not previously described in the prose binding. It is added to
document existing practice in the Aspeed devicetrees. Unfortunately
the property seems to predate the requirement that vendor-specific
properties be prefixed.

-Aspeed Vectored Interrupt Controller
-
-These bindings are for the Aspeed interrupt controller. The AST2400 and
-AST2500 SoC families include a legacy register layout before a re-designed
-layout, but the bindings do not prescribe the use of one or the other.
-
-Required properties:
-
-- compatible : "aspeed,ast2400-vic"
- "aspeed,ast2500-vic"
-
-- interrupt-controller : Identifies the node as an interrupt controller
-- #interrupt-cells : Specifies the number of cells needed to encode an
- interrupt source. The value shall be 1.
-
-Example:
-
- vic: interrupt-controller@1e6c0080 {
- compatible = "aspeed,ast2400-vic";
- interrupt-controller;
- #interrupt-cells = <1>;
- reg = <0x1e6c0080 0x80>;
- };
