Subject: [RFC/PATCH 05/18] ravb: Exclude gPTP feature support for RZ/G2L
Date: Thu, 23 Sep 2021 15:08:00 +0100	[thread overview]
Message-ID: <20210923140813.13541-6-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20210923140813.13541-1-biju.das.jz@bp.renesas.com>

R-Car supports gPTP feature whereas RZ/G2L does not support it.
This patch excludes gtp feature support for RZ/G2L by enabling
no_gptp feature bit.
