From 7388fa8acfce2c3b41babc53c3f3d0b247b098af Mon Sep 17 00:00:00 2001 From: Lad Prabhakar Date: Wed, 27 Oct 2021 14:45:06 +0100 Subject: [PATCH] dt-bindings: pincfg-node: Add "output-impedance-ohms" property On RZ/G2L SoC for Group-B pins, output impedance can be configured. This patch documents "output-impedance-ohms" property in pincfg-node.yaml so that other platforms requiring such feature can make use of this property.
