[PATCH] ARM: EXYNOS: Use platform device name as power domain name

From: Krzysztof Kozlowski
Date: Tue Feb 10 2015 - 07:57:29 EST


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
