Subject: [PATCH v6 1/6] drm/bridge: sii902x: add input_bus_flags
Date: Tue, 2 Apr 2019 10:29:10 +0300 [thread overview]
Message-ID: <04c0665a905df954544a640536f890a14e222fa6.1554146714.git.jsarha@ti.com> (raw)
In-Reply-To: <cover.1554146714.git.jsarha@ti.com>
From: Tomi Valkeinen <tomi.valkeinen@ti.com>
The driver always sets InputBusFmt:EDGE to 0 (falling edge).
Add drm_bridge_timings's input_bus_flags to reflect that the bridge
samples on falling edges.
