Subject: [RFC][PATCH 9/14] ARM: shmobile: Move sh7372's PM domain objects to a table
Date: Mon, 16 Jul 2012 21:26:37 +0000	[thread overview]
Message-ID: <201207162326.37644.rjw@sisk.pl> (raw)
In-Reply-To: <201207162315.49073.rjw@sisk.pl>

From: Rafael J. Wysocki <rjw@sisk.pl>

Instead of giving a name to every sh7372's PM domain object, put them
all into a table and use rmobile_init_domains(), introduced by a
previous patch, for initializing them all altogether.  Also, use
pm_genpd_add_subdomain_names() for adding subdomains to the PM
domains and pm_genpd_poweron_name() for turning on the A4S domain
when preparing for system suspend.
