[PATCH v4 0/3] Convert Xilinx XADC binding to YAML and related cleanups

[Pramod Maurya <pramod.nexgen@gmail.com>]

This series converts the Xilinx XADC device tree binding from the legacy
plain-text format to a validated YAML schema, fixes a checkpatch alignment
warning in the axis-fifo staging driver, and adds a YAML DT binding for
the Xilinx AXI-Stream FIFO IP core.

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.
