Solving Devicetree Issues, part 3.0
summary
Updates to device tree tooling show concrete results: DTX_diff is mainline (builds a canonical DTS view), dt2config generates the needed Kconfig lines from a DTS (now in mainline 4.8-rc1), and a new debug flow uses kernel printk hooks plus a parser called dt_prop to correlate which properties are present, accessed, or missing. The workflow finds real bugs (example: a qcom charge enable/disable inversion), requires enabling debug at boot, and has patches/examples on the elinux wiki.
