[PATCH RFC v2 07/12] PM / Domains: export pm_genpd_lookup_name
From: Amit Daniel Kachhap <hidden>
Date: 2014-11-24 13:17:40
Also in:
linux-arm-kernel, linux-pm, linux-samsung-soc, lkml
Subsystem:
driver core, kobjects, debugfs and sysfs, generic pm domains, hibernation (aka software suspend, aka swsusp), power management core, suspend to ram, the rest · Maintainers:
Greg Kroah-Hartman, "Rafael J. Wysocki", Danilo Krummrich, Ulf Hansson, Linus Torvalds
This API may be needed to set the power domain parent/child relationship in the power domain platform driver. The parent relationship is generally set after the child power domain is registered with the power domain subsystem. In this case, pm_genpd_lookup_name API might be useful.
