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. Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
Thanks for your patch!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
