[PATCH] dt-bindings: dma: snps,dma-spear1340: Fix data{-,_}width schema

From: Rob Herring
Date: Mon Mar 11 2024 - 18:25:43 EST


'data-width' and 'data_width' properties are defined as arrays, but the
schema is defined as a matrix. That works currently since everything gets
decoded in to matrices, but that is internal to dtschema and could change.
