[Sandeep] WE don't propose any API changes. This module for which we want to submit patches is a TI proprietary IP. We currently implement this as a character device and have a few IOCTL's. We do not follow the V4L2 framework and do not use any V4L2 IOCTLs. Can we continue to use it as a character driver? > > > > > Thanks, > > Sandeep > > -- > > To unsubscribe from this list: send the line "unsubscribe linux-media" > in > > the body of a message to majordomo@vger.kernel.org > > More majordomo info at http://vger.kernel.org/majordomo-info.html > > > > > Cheers, > Mauro -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
