Subject: [RFC PATCH 1/4] dt-bindings: pincfg-node: Add "output-impedance" property
Date: Thu, 30 Sep 2021 13:16:27 +0100 [thread overview]
Message-ID: <20210930121630.17449-2-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20210930121630.17449-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
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.
