Hi Pratyush, Thank you for the patch. On Fri, Dec 24, 2021 at 12:46:10AM +0530, Pratyush Yadav wrote: > Add media link validation to make sure incorrectly configured pipelines > are caught.

I think the commit message is a bit misleading. The default link validation function ensures that formats on the source and sink sides of a link match. It doesn't compare the formats on the sink and source pads of the subdev. Whether the subdev can transcode or not is thus not relevant here. > Signed-off-by: Pratyush Yadav <p.yadav@ti.com> > > --- > > Changes in v5: > - New in v5. > > drivers/media/platform/cadence/cdns-csi2rx.c | 5 +++++ > 1 file changed, 5 insertions(+) > > diff --git a/drivers/media/platform/cadence/cdns-csi2rx.c b/drivers/media/platform/cadence/cdns-csi2rx.c > index 53659776a906..119c7540c75a 100644 > --- a/drivers/media/platform/cadence/cdns-csi2rx.c > +++ b/drivers/media/platform/cadence/cdns-csi2rx.c > @@ -492,6 +492,10 @@ static const struct v4l2_subdev_ops csi2rx_subdev_ops = { > .pad = &csi2rx_pad_ops, > }; > > +static struct media_entity_operations csi2rx_media_ops = { static const Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> > + .link_validate = v4l2_subdev_link_validate, > +}; > + > static int csi2rx_async_bound(struct v4l2_async_notifier *notifier, > struct v4l2_subdev *s_subdev, > struct v4l2_async_subdev *asd) > @@ -691,6 +695,7 @@ static int csi2rx_probe(struct platform_device *pdev) > for (i = CSI2RX_PAD_SOURCE_STREAM0; i < CSI2RX_PAD_MAX; i++) > csi2rx->pads[i].flags = MEDIA_PAD_FL_SOURCE; > csi2rx->subdev.flags |= V4L2_SUBDEV_FL_HAS_DEVNODE; > + csi2rx->subdev.entity.ops = &csi2rx_media_ops; > > ret = media_entity_pads_init(&csi2rx->subdev.entity, CSI2RX_PAD_MAX, > csi2rx->pads);

Add media link validation to make sure incorrectly configured pipelines are caught. Since there is no support for transcoding, rely on the default link validation function to make sure formats across source and sink pads are the same.
