Provide a means to determine this based on the feature flags of the hardware configuration structs. Signed-off-by: Kieran Bingham Reviewed-by: Laurent Pinchart --- This could be a feature to designate that there is no interlaced support, which would then negate the need to add extra feature flags to the existing targets... But that's a 'non-feature' rather than a 'feature', so this way at least reads better. Tested on Salvator-XS (H3) by removing the flag and verifying interlaced modes are rejected. drivers/gpu/drm/rcar-du/rcar_du_crtc.c | 14 +++++++++++ drivers/gpu/drm/rcar-du/rcar_du_drv.c | 32 +++++++++++++++++--------- drivers/gpu/drm/rcar-du/rcar_du_drv.h | 1 + 3 files changed, 36 insertions(+), 11 deletions(-) diff --git a/drivers/gpu/drm/rcar-du/rcar_du_crtc.c b/drivers/gpu/drm/rcar-du/rcar_du_crtc.c index 15dc9caa128b..4b43d8329695 100644 --- a/drivers/gpu/drm/rcar-du/rcar_du_crtc.c +++ b/drivers/gpu/drm/rcar-du/rcar_du_crtc.c @@ -684,11 +684,25 @@ static void rcar_du_crtc_atomic_flush(struct drm_crtc *crtc, rcar_du_vsp_atomic_flush(rcrtc);
