If it's too difficult to get the imx219 csi-2 transmitter into the

Can you try the attached change on top of the version 5 patchset?
If that doesn't work then you're just going to have to fix the bug
in imx219.
That patch gets me past that hurdle, only to reveal that there's another
issue:
Yeah, ipu_cpmem_set_image() failed because it doesn't recognize the
bayer formats. Wait, didn't we fix this already? I've lost track.
Ah, right, we were going to move this support into the IPUv3 driver,
but in the meantime I think you had some patches to get around this.
