    Subject[RFC][PATCH 2/5] PM / shmobile: Allow device latencies to be specified directly
    Date

    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.
