Subject[PATCH v2 1/2] dt-bindings: net: dp83826: support TX data voltage tuning
Date
Add properties ti,cfg-dac-minus-one-milli-percent and
ti,cfg-dac-plus-one-milli-percent to support voltage tuning
of logical levels -1/+1 of the MLT-3 encoded TX data.

Signed-off-by: Catalin Popescu <catalin.popescu@leica-geosystems.com>

Changes in v2:
- squash the 2 DT bindings patches in one single patch
- drop redundant "binding" from the DT bindings patch title
- rename DT properties and define them as percentage
- add default value for each new DT property
