[PATCH v2 4/4] drm/mipi-dsi: Drop MIPI_DSI_MODE_VSYNC_FLUSH flag
Posted by Philipp Zabel 3 months, 1 week ago
Drop the unused MIPI_DSI_MODE_VSYNC_FLUSH flag. Whether or not a display
FIFO flush on vsync is required to avoid sending garbage to the panel is
not a property of the DSI link, but of the integration between display
controller and DSI host bridge.
