Changes in version 2:
- rebased the patch.
This patch is against the 'renesas-devel-20170125-v4.10-rc5' of Simon
Horman's
'renesas.git' repo. It's only meaningful if the DRM driver patches
I've
just
posted are applied.
Forgot to note that without this patch the DU driver fails to link to
VSPD and probe correctly, so there's no video signal. So it makes sense
to
apply before the DU driver patch (once it's ACKed for merge)...
Doesn't that translate to breaking the DT ABI? Is there someway we can
avoid doing that?
It doesn't -- if this patch is merged ahead of the DU patches.
Perhaps I'm misunderstanding, but if you require a DTS patch to be
merged before a driver change then doesn't this mean that older DTBs
will stop working with newer kernels and the user is forced to update
the DTB to avoid breakage?
Yes, it seems so. :-(
It would be nice if older DTBs could keep on working as before and the
DU driver modification would work both with connected VSPs and also
keep on working as before in case the VSP connection is not present in
DT.
I'll try to look into that...
