Up until now the VIN was capable to convert any of its supported input mbus
formats to any of it's supported output pixel formats. With the addition of
RAW formats this is no longer true.
This patch invalidates the pipeline by adding a check if given vin input
format can be converted to supported output pixel format.

I like this patch I think there is a typo bellow and patch [1] have been
merged in the media-tree which unfortunately addes one more thing to do
in this patch. In rvin_enum_fmt_vid_cap() there is a TODO noted for what
needs to be done. In imagine the fix is simple and the end result would
look something like this.
switch (f->mbus_code) {
case 0:
case MEDIA_BUS_FMT_YUYV8_1X16:
case MEDIA_BUS_FMT_UYVY8_1X16:
case MEDIA_BUS_FMT_UYVY8_2X8:
case MEDIA_BUS_FMT_UYVY10_2X10:
case MEDIA_BUS_FMT_RGB888_1X24:
break;
case MEDIA_BUS_FMT_SRGGB8_1X8:
if (f->index)
return -EINVAL;
f->pixelformat = V4L2_PIX_FMT_SRGGB8;
return 0;
case default:
return -EINVAL;
}

This is not right is it?
Should you not add a case for MEDIA_BUS_FMT_SRGGB8_1X8 instead of taking
over MEDIA_BUS_FMT_RGB888_1X24?

Agreed, I blindly took this suggestion from your previous comments [1].

Yes, also please test it as you point out bellow my last suggesting had
a typo which would break it ;-)

Add support for MEDIA_BUS_FMT_SRGGB8_1X8 format in rcar-vin by setting
format type to RAW8 in VNMC register and appropriately setting the bpp
and bytesperline to enable V4L2_PIX_FMT_SRGGB8.
