Another round of removing redundant minItems/maxItems from new schema in the recent merge window. If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.

A Rockchip DRM iommu translates io virtual addresses to physical addresses for
|
|
its master device. Each slave device is bound to a single master device and
|
|
shares its clocks, power domain and irq.
|
|
|
|
For information on assigning IOMMU controller to its peripheral devices,
|
|
see generic IOMMU bindings.
