[RFC PATCH 1/4] dt-bindings: pincfg-node: Add "output-impedance" property

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

 



On RZ/G2L SoC for Group-B pins, output impedance can be configured.
This patch documents "output-impedance" property in pincfg-node.yaml so
that other platforms requiring such feature can make use of this property.
