From 7496fcbe8a643097efc061160e1c3b65ee2fa350 Mon Sep 17 00:00:00 2001 From: Amit Daniel Kachhap Date: Mon, 15 Dec 2014 09:08:59 +0530 Subject: PM / Domains: Export of_genpd_get_from_provider function This function looks up a PM domain form the provider. This will be useful to add parent/child domain relationship from the SoC specific code. The caller of the function must make sure that PM domain provider is already registered.
