[PATCH] ASoC: dt-bindings: sound: renesas,r9a09g047: Fix dma-names list and ports schema
Posted by John Madieu 4 days, 12 hours ago
Express the dvc/src/ssiu dma-names as an items list rather than an
allOf-wrapped single schema, and drop the now-redundant maxItems. Fix
the ports container to reference graph.yaml's ports definition instead
of port-base (a ports container is not itself a port), keeping
port-base on the port@N children, and constrain each playback/capture
phandle-array entry to a single phandle.

While at it, drop the unused top-level #address-cells/#size-cells since
no child node uses a unit address and the ports node provides its own,
require interrupts/dmas/dma-names on the src sub-nodes to match the
ssi/ssiu sub-nodes and the driver, pin clocks and resets to their fixed
counts (47 and 14) to match the clock-names/reset-names lists, and put
compatible and reg first in the example.

Fixes: a86fd3c20218 ("ASoC: dt-bindings: sound: Add DT binding for RZ/G3E sound")

All you need is:

maxItems: 5
items:
  const: tx

(The schema form (vs. list form) of 'items' applies to all items.)

What happened to the first clock cells (CPG_MOD)?
