That's every 'assigned-clocks'.

The schema only allows the exact list below. You'll need an if/then schema to define the different combinations. Or a 'oneOf' schema if there's different possibilities for just the sc7180. There shouldn't be though. A given chip either has a clock or it doesn't. > + items: > + - const: bus > + - const: iface > + - const: rot > + - const: lut > + - const: core > + - const: vsync > + > + interrupts: > + maxItems: 1 > + > + ports: > + type: object > + description: | > + Contains the list of output ports from DPU device.
