Subject: [RFC PATCH 3/4] dt-bindings: pinctrl: renesas,rzg2l-pinctrl: Add output-impedance property
Date: Thu, 30 Sep 2021 13:16:29 +0100 [thread overview]
Message-ID: <20210930121630.17449-4-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <20210930121630.17449-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
RZ/G2L SoC has two groups of pins, Group-A and Group-B. RZ/G2L SoC supports
configuring Output Impedance for Group-B pins (valid values 33/50/66/100).
