PM / OPP: take RCU lock in dev_pm_opp_get_opp_count

2014-12-18T00:42:49Z

A lot of callers are missing the fact that dev_pm_opp_get_opp_count needs to be called under RCU lock. Given that RCU locks can safely be nested, instead of providing *_locked() API, let's take RCU lock inside dev_pm_opp_get_opp_count() and leave callers as is.

PM / OPP: fix warning in of_free_opp_table()

2014-12-18T00:42:49Z

Not having OPP defined for a device is not a crime, we should not splat warning in this case. Also, it seems that we are ready to accept invalid dev (find_device_opp will return ERR_PTR(-EINVAL) then) so let's not crash in dev_name() in such case.

PM / OPP: add some lockdep annotations

2014-12-18T00:42:49Z

Certain OPP APIs need to be called under RCU lock; let's add a few rcu_lockdep_assert() calls to warn about potential misuse. Signed-off-by: Dmitry Torokhov Acked-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki

PM / Domains: Export of_genpd_get_from_provider function

2014-12-17T01:33:34Z

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. Reviewed-by: Ulf Hansson Signed-off-by: Amit Daniel Kachhap Signed-off-by: Rafael J. Wysocki

PM / OPP: do error handling at the bottom of dev_pm_opp_add_dynamic()

2014-12-10T21:18:34Z

This makes it less error prone and moves common resource deallocation at a single place. Signed-off-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki

PM / OPP: handle allocation of device_opp in a separate routine

2014-12-10T21:18:34Z

Get the 'device_opp' allocation code into a separate routine to keep only the necessary part in dev_pm_opp_add_dynamic(). Also do s/sizeof(struct device_opp)/sizeof(*dev_opp) and remove the print message on kzalloc() failure as checkpatch warns for that. Signed-off-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki

PM / OPP: reuse find_device_opp() instead of duplicating code

2014-12-10T21:18:34Z

Reuse find_device_opp() in opp_set_availability() instead of duplicating code. Signed-off-by: Viresh Kumar Signed-off-by: Rafael J. Wysocki
