The power domain nodes in DTS may be very generic (e.g. "power-domain"
for Exynos 5420) making it very hard to debug:
$ cat /sys/kernel/debug/pm_genpd/pm_genpd_summary
domain status slaves
power-domain on
Use platform device name instead so the names will be a little more user
friendly:
domain status slaves
100440e0.power-domain on

Looks good to me. This patch is very useful for debug.
