[PATCH v2 1/5] drm/bridge: sii902x: add input_bus_flags

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tomi Valkeinen <tomi.valkeinen@xxxxxx>

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.
