ovmerge is tool for merging DT overlay source files (*-overlay.dts),
flattening and sorting .dts files for easy comparison, displaying
the include tree, etc.
Build Instructions

Usage
Usage: ovmerge <options> <ovspec>
where <ovspec> is the name of an overlay, optionally followed by
a comma-separated list of parameters, each with optional '=<value>'
assignments. The presence of any parameters, or a comma followed by
no parameters, removes the parameter declarations from the merged
overlay to avoid a potential name clash.
and <options> are any of:
-b <branch> Read files from specified git branch
-c Include 'redo' comment with command line (c.f. '-r')
-e Expand mode - list non-skipped lines in order of inclusion
-h Display this help info
-i Show include hierarchy for each file
-l Like expand mode, but labels each line with source file
-n No .dts file header (just parsing .dtsi files)
-p Emulate Pi firmware manipulation
-r Redo command comment in named files (c.f. '-c')
-s Sort nodes and properties (for easy comparison)
-t Trace
-w Show warnings
