Subject: [PATCH 10/20] drm/bridge: tc358775: simplify lvds_link property
Date: Mon, 06 May 2024 15:34:39 +0200 [thread overview]
Message-ID: <20240506-tc358775-fix-powerup-v1-10-545dcf00b8dd@kernel.org> (raw)
In-Reply-To: <20240506-tc358775-fix-powerup-v1-0-545dcf00b8dd@kernel.org>
The LVDS link can either be a single link or a dual link. No need for a
u8. Replace it with a bool "lvds_dual_link".
