Hi all, This series reworks the device tree userspace view to be exposed via sysfs. I've been wanting to move to using kobjects to manage the device tree for a while now. It results in less code overall, and it gives us the userspace view "for free".
The first patch converts the device_nodes into kobjects and registers them under /sys/firmware/ofw/device-tree. The second removes the old /proc/device-tree support code and replaces it with a symlink from /proc/device-tree to the sysfs view. I attempted to also remove the virtual /proc/openprom filesystem, but unfortunately /proc/devicetree and /proc/openprom use different semantics. In /proc/devicetree the properties are exposed as raw binaries, but in /proc/openprom the properties are all converted into ascii string representation first. I've tested this series on ARM and embedded powerpc. I have build tested on SPARC and x86. Dave, I'm particularly interested to know how well this runs on SPARC. I think I've got it right, but I haven't tested the changes to the driver/of/pdt.c code. g.
