Subject: [RFC][PATCH 2/5] PM / shmobile: Allow device latencies to be specified directly
Date: Sat, 21 Jul 2012 23:54:14 +0200 [thread overview]
Message-ID: <201207212354.14958.rjw@sisk.pl> (raw)
In-Reply-To: <201207212349.18294.rjw@sisk.pl>
Make it possible to specify device start/stop and save/restore
state latencies directy when adding devices to PM domains. For
this purpose, introduce rmobile_add_device_to_domain_td() whose
third argument is a pointer to a struct gpd_timing_data object
containing device latency data.
