Furthermore, this header is not\neven strictly required as long as we don't have anything dealing with\nIPU3's stats and params (so yes, not for long, but...)\n\nI would not merge this patch and wait to have a real need for this\nheader. Then, let's see which version will be more convenient to use,\nand maybe update other headers as well.\n\nThanks\n  j\n\n\n> >\n> > Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>\n> > Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>\n> > ---\n> >  include/linux/intel-ipu3.h | 2779 ++++++++++++++++++++++++++++++++++++\n> >  1 file changed, 2779 insertions(+)\n> >  create mode 100644 include/linux/intel-ipu3.h\n> >\n> > diff --git a/include/linux/intel-ipu3.h b/include/linux/intel-ipu3.h\n> > new file mode 100644\n> > index 000000000000..f758c9ba230b\n> > --- /dev/null\n> > +++ b/include/linux/intel-ipu3.h\n> > @@ -0,0 +1,2779 @@\n> > +/* SPDX-License-Identifier: GPL-2.0 */\n> > +/* Copyright (C) 2017 -
