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@xxxxxxxxxx> Signed-off-by: Catalin Popescu <catalin.popescu@xxxxxxxxxxxxxxxxxxxx> --- 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 --- .../devicetree/bindings/net/ti,dp83822.yaml | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/Documentation/devicetree/bindings/net/ti,dp83822.yaml b/Documentation/devicetree/bindings/net/ti,dp83822.yaml index db74474207ed..8f4350be689c 100644 --- a/Documentation/devicetree/bindings/net/ti,dp83822.yaml +++ b/Documentation/devicetree/bindings/net/ti,dp83822.yaml @@ -62,6 +62,24 @@ properties: for the PHY.
