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

Correct, that's sitting out of tree because it requires either legacy code in arch/arm/mach-dove at the moment, or stuff for DT. Each time that I looked at the DT reserved memory stuff I've ended up giving up as it always seemed to be half complete, and the documentation was confusing (seemingly referring to things that weren't merged.) Maybe that's changed today, but I've not had a chance to look at it again. -- RMK's Patch system: http://www.armlinux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
