Patch 1 is v4 of the XADC binding conversion. Previous versions had the following issues that are now addressed: - v3: xlnx,channels was placed in patternProperties to satisfy the vendor-props.yaml meta-schema; dt-schema PR#195 (merged by Rob Herring) now allows commas in nodenames so it correctly lives in properties. A companion dt-schema update is needed to add xlnx,channels to the vendor-props.yaml explicit object exceptions (similar to the existing adi,channels entry). - v3: reg constraints inside channel subnodes used bare minimum/maximum keywords which are silently ignored on array types; the description now documents the valid range and reg uses maxItems: 1 per cell.yaml. - v3: xlnx,bipolar had a redundant type: boolean alongside the $ref to /schemas/types.yaml#/definitions/flag; the $ref already implies the boolean type so type: boolean is removed. Patches 2 and 3 are new additions to this series.
