[PATCH 0/5] DRM OF graph clean-up

[Rob Herring]

I've been unhappy with the OF graph API for some time and decided to 
do something about it. The problem is drivers have to do too much of the 
graph parsing and walking themselves. This has led to the same pattern 
duplicated over and over. This series adds 2 new helpers and adapts DRM 
drivers to use them. It only adds one new graph helper, but reduces the 
use of the others which I hope to remove at some point. But we're not 
there yet.

There's a few other things I'd like to clean-up.

The Armada and Rockchip drivers remain oddballs with their own graph 
parsing. I can't see how the armada driver even can work. There's 
nothing to instantiate the armada-drm device either in DT or the kernel.

The omapdrm driver still has some custom helpers similar to the common 
ones, but still slightly different. It got to be more changes than I 
wanted to make to address.

Build tested only (and probably not every last driver).
