Subject: [RFC][PATCH 10/14] ARM: shmobile: Move r8a7740's PM domain objects to a table
From: Rafael J. Wysocki <rjw@...k.pl>
Instead of giving a name to every r8a7740'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 A3SP as a subdomain of A4S.
