It seems maxItems should have been 4 in the first place and should remain
unchanged after removing the load state power domain. With this patch:
- if:
properties:
compatible:
contains:
enum:
- qcom,sc7180-mpss-pas
then:
properties:
power-domains:
items:
- description: CX power domain
- description: MX power domain
- description: MSS power domain
power-domain-names:
items:
- const: cx
- const: mx
- const: mss
