[PATCH 0/4] PM / Domains: Allow performance state propagation

2018-11-04 Thread Viresh Kumar
Hi, This series adds performance state propagation support in genpd core. The propagation happens from the sub-domains to their masters. More details can be found in the individual commit logs. This is tested on hikey960 by faking power domains in such a way that the CPU devices have two power

[PATCH 1/4] OPP: Add dev_pm_opp_xlate_performance_state() helper

2018-11-04 Thread Viresh Kumar
Introduce a new helper dev_pm_opp_xlate_performance_state() which will be used to translate from pstate of a device to another one. Initially this will be used by genpd to find pstate of a master domain using its sub-domain's pstate. Signed-off-by: Viresh Kumar --- drivers/opp/core.c | 49

[PATCH 4/4] PM / Domains: Propagate performance state updates

2018-11-04 Thread Viresh Kumar
This commit updates genpd core to start propagating performance state updates to master domains that have their set_performance_state() callback set. A genpd handles two type of performance states now. The first one is the performance state requirement put on the genpd by the devices and

[PATCH 3/4] PM / Domains: Factorize dev_pm_genpd_set_performance_state()

2018-11-04 Thread Viresh Kumar
Separate out _genpd_set_performance_state() and _genpd_reeval_performance_state() from dev_pm_genpd_set_performance_state() to handle performance state update related stuff. This will be used by a later commit. Signed-off-by: Viresh Kumar --- drivers/base/power/domain.c | 104
