Subject: DT schema warnings on Risc-V virt machine
Date: Wed, 3 Aug 2022 11:05:52 -0600	[thread overview]
Message-ID: <20220803170552.GA2250266-robh@kernel.org> (raw)

Hey folks,

FYI, I ran DT validation on the Risc-V 'virt' machine and these are the 
warnings:

/home/rob/riscv-virt.dtb: cpu@0: riscv,isa:0: 'rv64imafdcsuh' is not one of ['rv64imac', 'rv64imafdc']
        From schema: /home/rob/proj/git/linux-dt/Documentation/devicetree/bindings/riscv/cpus.yaml
/home/rob/riscv-virt.dtb: soc: poweroff: {'value': [[21845]], 'offset': [[0]], 'regmap': [[4]], 'compatible': ['syscon-poweroff']} should not be valid under {'type': 'object'}
        From schema: /home/rob/proj/git/dt-schema/dtschema/schemas/simple-bus.yaml
/home/rob/riscv-virt.dtb: soc: reboot: {'value': [[30583]], 'offset': [[0]], 'regmap': [[4]], 'compatible': ['syscon-reboot']} should not be valid under {'type': 'object'}
        From schema: /home/rob/proj/git/dt-schema/dtschema/schemas/simple-bus.yaml
/home/rob/riscv-virt.dtb: uart@10000000: $nodename:0: 'uart@10000000' does not match '^serial(@.*)?$'
        From schema: /home/rob/proj/git/linux-dt/Documentation/devicetree/bindings/serial/8250.yaml
/home/rob/riscv-virt.dtb: plic@c000000: compatible: 'oneOf' conditional failed, one must be fixed:
        'sifive,plic-1.0.0' is not one of ['sifive,fu540-c000-plic', 'starfive,jh7100-plic', 'canaan,k210-plic']
        'sifive,plic-1.0.0' is not one of ['allwinner,sun20i-d1-plic']
        'sifive,plic-1.0.0' was expected
        'thead,c900-plic' was expected
        From schema: /home/rob/proj/git/linux-dt/Documentation/devicetree/bindings/interrupt-controller/sifive,plic-1.0.0.yaml
/home/rob/riscv-virt.dtb: plic@c000000: '#address-cells' is a required property

        From schema: /home/rob/proj/git/linux-dt/Documentation/devicetree/bindings/timer/sifive,clint.yaml

        From schema: /home/rob/proj/git/linux-dt/Documentation/devicetree/bindings/timer/sifive,clint.yaml


Also from the 'spike' machine:

/home/rob/riscv-spike.dtb: cpu@0: riscv,isa:0: 'rv64imafdcsuh' is not one of ['rv64imac', 'rv64imafdc']
        From schema: /home/rob/proj/git/linux-dt/Documentation/devicetree/bindings/riscv/cpus.yaml
/home/rob/riscv-spike.dtb: clint@2000000: compatible:0: 'sifive,clint0' is not one of ['sifive,fu540-c000-clint', 'starfive,jh7100-clint', 'canaan,k210-clint']
        From schema: /home/rob/proj/git/linux-dt/Documentation/devicetree/bindings/timer/sifive,clint.yaml
/home/rob/riscv-spike.dtb: clint@2000000: compatible:1: 'sifive,clint0' was expected
        From schema: /home/rob/proj/git/linux-dt/Documentation/devicetree/bindings/timer/sifive,clint.yaml


There could also be other warnings from non-default configurations.

To reproduce, dump the dtb and run:

dt-validate -p Documentation/devicetree/bindings/processed-schema.json riscv-spike.dtb 

(processed-schema.json is from kernel validation run)
