Subject: [PATCH 6/7] drm: adv7511: Add link_config feature bit to struct adv7511_chip_info
Date: Sun, 13 Aug 2023 19:05:11 +0100	[thread overview]
Message-ID: <20230813180512.307418-7-biju.das.jz@bp.renesas.com> (raw)
In-Reply-To: <20230813180512.307418-1-biju.das.jz@bp.renesas.com>

The ADV7511 needs link configuration whereas ADV75{33,35} does not need
it. Add a feature bit link_config to struct adv7511_chip_info to handle
this difference.
