I think the restrictions already in the file become incorrect with this
patch:
- if:
properties:
compatible:
contains:
enum:
- renesas,r9a07g043u-irqc
- renesas,r9a08g045-irqc
then:
properties:
interrupts:
minItems: 42
interrupt-names:
minItems: 42
required:
- interrupt-names
This used to require all 42 interrupts for the two compatibles here
and at least the first 41 otherwise. Now you've increased the number of
interrupts to 48 thereby removing the upper limits on the existing
devices.
Given the commit message, I figure that providing 48 interrupts for
(at least some of) those devices would be incorrect?
Cheers,
Conor.
