The DU driver has recently gained two new feature flags, 
RCAR_DU_FEATURE_INTERLACED and RCAR_DU_FEATURE_TVM_SYNC. I believe that both 
should be set here. Could you please confirm (and test) ?

I'd write this "and one (currently unsupported) analog video output" to match 
the other device entries. With this fixed,

I can confirm that both feature flags need to be set and all the test pass.
Will send a new version for this.
