From: Emanuele Ghidoli <[email protected]> The component datasheet recommends, to reduce power consumption, transitioning to LP mode on every video line.
Enable the MIPI_DSI_MODE_VIDEO_NO_HFP and MIPI_DSI_MODE_VIDEO_NO_HBP flags so that the bridge can enter LP mode during the horizontal front porch and back porch periods.
