PM / tools: sleepgraph and bootgraph: upgrade to v5.2
bootgraph & sleepgraph: - funnel all prints through the pprint function - remove superfluous print calls, arrange them in single blocks - flush stdout on every print, enables log capture on hang sleepgraph: - in -summary, if all tests have the same host+kernel+mode, add to title - update verbose device detail print to include machine suspend/resume - match tKernSus and tKernRes to pm_prepare/restore_console - fully support multiple suspend/resumes in a single timeline - enable various disk modes (disk-suspend, disk-test_resume, etc) - add warnings when -display (xset) fails Signed-off-by: Todd Brandt <todd.e.brandt@linux.intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
