On which bus? The bridge has input and output.
Copy the bus flags from the bridge timings if a bridge is in use.

Good point, will change in v3 to:
"A bridge might require specific settings for the pixel data on its input bus. Those are specified through optional bus timings. Copy the bridges input bus flags as to the imxpd bus flags."

imxpd->dev = dev;
ret = imx_pd_register(drm, imxpd);
