The TVP5150 DT bindings specify a single output port (port 0) that corresponds to the video output pad (pad 1, DEMOD_PAD_VID_OUT). Signed-off-by: Philipp Zabel <p.zabel@xxxxxxxxxxxxxx> --- I'm trying to get this to work with a TVP5150 analog TV decoder, and the first problem is that this device doesn't have pad 0 as its single output pad. Instead, as a MEDIA_ENT_F_ATV_DECODER entity, it has for pads (input, video out, vbi out, audio out), and video out is pad 1, whereas the device tree only defines a single port (0). --- drivers/staging/media/imx/imx-media-dev.c | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/drivers/staging/media/imx/imx-media-dev.c b/drivers/staging/media/imx/imx-media-dev.c index 17e2386a3ca3a..c52d6ca797965 100644 --- a/drivers/staging/media/imx/imx-media-dev.c +++ b/drivers/staging/media/imx/imx-media-dev.c @@ -267,6 +267,15 @@ static int imx_media_create_link(struct imx_media_dev *imxmd, source_pad = link->local_pad; sink_pad = link->remote_pad; + /* + * If the source subdev is an analog video decoder with a single source + * port, assume that this port 0 corresponds to the DEMOD_PAD_VID_OUT + * entity pad. + */ + if (source->entity.function == MEDIA_ENT_F_ATV_DECODER && + local_sd->num_sink_pads == 0 && local_sd->num_src_pads == 1) + source_pad = DEMOD_PAD_VID_OUT; + v4l2_info(&imxmd->v4l2_dev, "%s: %s:%d -> %s:%d\n", __func__, source->name, source_pad, sink->name, sink_pad); -- 2.11.0
