[PATCH v5 3/6] dt-bindings: media: Document data-enable-active property

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add 'data-enable-active' property to endpoint node properties list.

The property allows to specify the polarity of the data-enable signal, which
when in active state determinates when data lines have to sampled for valid
pixel data.
