>From my local testing (albiet the shambles that is bits of v4l2) setting dev->of_node is not necessary for imx-drm - imx-drm comes up fine without. Fixing _this_ code for that is not too difficult - it's a matter of: priv->sd.of_node = pdata->of_node; in imx_csi_probe(). However, the difficult bit is the poor state of code in v4l2, particularly the v4l2-async crap. Right now, fixing the module autoloading will oops the kernel, so it's best that module autoloading remains broken for the time being. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net.
