[v6,11/11] drm: rcar-du: Support interlaced video output through vsp1

  From: Kieran Bingham <kieran.bingham+renesas@ideasonboard.com>

Use the newly exposed VSP1 interface to enable interlaced frame support
through the VSP1 LIF pipelines.

The DSMR register is updated to set the ODEV flag on interlaced
pipelines, thus defining an interlaced stream as having the ODD field
located in the second half (BOTTOM) of the frame buffer.

Hi Kieran,

It seems that some patches from this series were merged already,
while others (including this one) weren't.

Could you please generate a v7 of this series with the stuff that
it is still missing?

I'll mark the remaining v6 patches as Superseded on Patchwork.

Thanks!
Mauro

This patch should be the only one not merged yet. It will get merged in v4.20 
through Dave's tree.
