With the above change here in snps,dw-apb-ssi.yaml:
- if:
properties:
compatible:
contains:
const: amd,pensando-elba-spi
then:
properties:
reg:
items:
minimum: 0
maximum: 3
required:
- amd,pensando-elba-syscon
else:
properties:
amd,pensando-elba-syscon: false
this is the result:
$ make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml
LINT Documentation/devicetree/bindings
CHKDT Documentation/devicetree/bindings/processed-schema.json
SCHEMA Documentation/devicetree/bindings/processed-schema.json
DTC_CHK arch/arm64/boot/dts/amd/elba-asic.dtb
/home/brad/linux.v10/arch/arm64/boot/dts/amd/elba-asic.dtb: spi@...0: reg:0: [0, 10240, 0, 256] is too long
From schema: /home/brad/linux.v10/Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml
/home/brad/linux.v10/arch/arm64/boot/dts/amd/elba-asic.dtb: spi@...0: system-controller@0:reg: [[0], [1], [2], [3]] is too long
From schema: /home/brad/linux.v10/Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml
The binding snps,dw-apb-ssi.yaml has patternProperties defined this way:
patternProperties:
"^.*@[0-9a-f]+$":
type: object
properties:
reg:
minimum: 0
maximum: 3
- Removing patternProperties makes the error go away indicating an issue with minimum/maximum regex check
and the number of items in the reg property which shouldn't be related.
- Changing patternProperties to this makes the error go away.
patternProperties:
"^.*@[0-9a-f]+$":
type: object
properties:
reg:
maxItems: 4
- Using spmi.yaml as a reference and changing patternProperties to the following:
patternProperties:
"^.*@[0-9a-f]+$":
type: object
properties:
reg:
items:
- maxItems: 4
items:
- minimum: 0
- maximum: 3
required:
- reg
results in:
$ make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/spi/snps,dw-apb-ssi.yaml

- With this version for patternProperties, to retain minimum/maximum, the original error occurs:

"^.*@[0-9a-f]+$":
type: object
properties:
reg:
items:
- minItems: 1
items:
