I'd put it under gpu/drm/imx/epdc, perhaps.

- struct mxc_epdc *priv = to_mxc_epdc(drm);
- int ret;
- priv->connector.dpms = DRM_MODE_DPMS_OFF;
- priv->connector.polled = 0;
- drm_connector_helper_add(&priv->connector,

return ret;- ret = of_get_display_timing(drm->dev->of_node, "timing", &priv->timing);
- if (ret)
return ret;- return 0;
Possible to simplify to:
return of_get_display_timing(drm->dev->of_node, "timing", &priv->timing);
