Current version in -next uses > of_graph_get_remote_node() to replace all those lines you have added (see Rob > Herring's series to introduce of_graph_get_remote_node() function) Hm, I'm not on Linus' master tree [1] and so I thought I was quite up to date :) Still I made a check of linux-next and don't see any changes in "drivers/gpu/drm/arm" compared to Linus' tree. [1] http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/gpu/drm/arm?id=e4563f6ba71792c77aeccb2092cc23149b44e642 [2] http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/drivers/gpu/drm/arm?id=e4563f6ba71792c77aeccb2092cc23149b44e642 Could you please clarify which exact tree did you mean? Anyways I just tried to rebase my patch on top of linux-next tree and now video output is broken for me - I only see some garbage on top of the screen so I'll need to investigate it first before moving forward with stuff you proposed :) -Alexey��.n��������+%������w��{.n����z�{��ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
