dt-bindings: interrupt-controller: loongson,liointc: Fix dtbs_check warning for interrupt-names
The Loongson-2K0500/2K1000 CPUs have 64 interrupt sources as inputs, and a route-mapped node handles up to 32 interrupt sources, so two liointc nodes are defined in dts{i}. Of course, we have to make sure that the routing outputs ("intx") of the two nodes do not conflict, i.e. "int0" can only be used as a routing output for one of them. Therefore, "interrupt-names" should be defined as "pattern". In addition, since "interrupt-names" and "interrupts" are one-to-one correspondence, we pass it to get the corresponding interrupt number in the driver. Setting it to "required" does not break ABI, because it is already logically represented as "required". This fixes dtbs_check warning: DTC_CHK arch/loongarch/boot/dts/loongson-2k0500-ref.dtb arch/loongarch/boot/dts/loongson-2k0500-ref.dtb: interrupt-controller@1fe11440: interrupt-names:0: 'int0' was expected From schema: Documentation/devicetree/bindings/interrupt-controller/loongson,liointc.yaml arch/loongarch/boot/dts/loongson-2k0500-ref.dtb: interrupt-controller@1fe11440: Unevaluated properties are not allowed ('interrupt-names' was unexpected) From schema: Documentation/devicetree/bindings/interrupt-controller/loongson,liointc.yaml DTC_CHK arch/loongarch/boot/dts/loongson-2k1000-ref.dtb arch/loongarch/boot/dts/loongson-2k1000-ref.dtb: interrupt-controller@1fe01440: interrupt-names:0: 'int0' was expected From schema: Documentation/devicetree/bindings/interrupt-controller/loongson,liointc.yaml arch/loongarch/boot/dts/loongson-2k1000-ref.dtb: interrupt-controller@1fe01440: Unevaluated properties are not allowed ('interrupt-names' was unexpected) From schema: Documentation/devicetree/bindings/interrupt-controller/loongson,liointc.yaml Acked-by: Jiaxun Yang <jiaxun.yang@flygoat.com> Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Binbin Zhou <zhoubinbin@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
