Also, are you > on the hook for pull requests? Hm, I guess that was too implicit. The idea is that anything small goes directly into drm-misc-next, and only really huge stuff (I've picked an arbitrary limit of 20+ patches) goes into a topic branch. That's definitely something we need to refine as we go I think. But for one-off patches I think the common tree is really a benefit, since no coordination between subsytem wide refactoring and driver patches is needed through pull requests. And yes since it's the same tree I'm volunteering for pull requests. dim status tells me when there's something pending (I wrote that a bit ago as prep to make drm-misc easy for me). -Daniel > > Sean > > > > > v2: Spelling fixes (Anholt). > > > > Cc: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx> > > Cc: Eric Anholt <eric@xxxxxxxxxx> > > Cc: Sean Paul <seanpaul@xxxxxxxxxxxx> > > Cc: Gerd Hoffmann <kraxel@xxxxxxxxxx> > > Cc: Mark Yao <mark.yao@xxxxxxxxxxxxxx> > > Cc: Shawn Guo <shawnguo@xxxxxxxxxx> > > Acked-by: Sean Paul <seanpaul@xxxxxxxxxxxx> > > Acked-by: Gerd Hoffmann <kraxel@xxxxxxxxxx> > > Acked-by: Boris Brezillon <boris.brezillon@xxxxxxxxxxxxxxxxxx> > > Acked-by: Eric Anholt <eric@xxxxxxxxxx> > > Signed-off-by: Daniel Vetter <daniel.vetter@xxxxxxxxx> > > --- > > drm-misc.rst | 30 ++++++++++++++++++++++++++++++ > > 1 file changed, 30 insertions(+) > > > > diff --git a/drm-misc.rst b/drm-misc.rst > > index 3d711ec60047..7f7233cf3c61 100644 > > --- a/drm-misc.rst > > +++ b/drm-misc.rst > > @@ -93,6 +93,36 @@ Right now the only hard merge criteria are: > > * See also the extensive `committer guidelines for drm-intel > > <drm-intel.html#committer-guidelines>`_. > > > > +Small Drivers > > +============= > > + > > +Small drivers, where a full tree is overkill, can be maintained in drm-misc.
