POPESCU Catalin Feb. 12, 2024, 7:46 a.m. UTC 
Add properties ti,cfg-dac-minus-one-bp/ti,cfg-dac-plus-one-bp
to support voltage tuning of logical levels -1/+1 of the MLT-3
encoded TX data.

Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
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

Changes in v3:
 - rename properties to "-bp" and change their admissible values
   accordingly

Changes in v4:
 - add reviewed-by tag
