Device tree nodes are already treated as objects, and we already want to expose them to userspace which is done using the /proc filesystem today. Right now the kernel has to do a lot of work to keep the /proc view in sync with the in-kernel representation. If device_nodes are switched to be kobjects then the device tree code can be a whole lot simpler. It also turns out that switching to using /sysfs from /proc results in smaller code and data size, and the userspace ABI won't change if /proc/device-tree symlinks to /sys/firmware/devicetree/base. v7: Add missing sysfs_bin_attr_init() v6: Add __of_add_property() early init fixes from Pantelis v5: Rename firmware/ofw to firmware/devicetree Fix updating property values in sysfs v4: Fixed build error on Powerpc Fixed handling of dynamic nodes on powerpc v3: Fixed handling of duplicate attribute and child node names v2: switch to using sysfs bin_attributes which solve the problem of reporting incorrect property size.
