Subject: [PATCH v3 08/20] ASoC: dt-bindings: tas27xx: document
 ti,sdout-force-zero-mask property

TAS2764 can be programmed to zero-fill/ignore certain TDM slots on a
shared I2S bus. Since this is a per-chip setting that is a consequence
of how it is implemented on a specific board, express this as a Devicetree
property.
