I also tested this on top of my v7 [1] of rpm power domain series and things continue to work as expected for the cx/mx propagation so I am fine with my Tested-by on all the patches.

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 domains and both of them have the same master domain. The CPU device, as well as its power domains have "required-opps" property set and the performance requirement from the CPU eventually configures all the domains (2 sub-domains and 1 master). Based on opp/linux-next branch (which is 4.20-rc1 + multiple-power-domain-support-in-opp-core + some OPP fixes). Rajendra has already tested the previous version of this series and so I have included his Tested-by for all patches. V2->V3: - Include Ulf's patch (sent separately earlier) with this series. - The performance state update code doesn't rely anymore on the power on/off state of the genpd, it sets and propagates rate in all cases. - That simplified a lot of code from V2 in _genpd_power_on(). - commit logs improved for few commits. - s/mstate/master_state/ - and few more minor changes. v1->V2: - First patch (1/5) is new and an improvement to earlier stuff. - Move genpd_status_on() check to _genpd_reeval_performance_state() from _genpd_set_performance_state(). - Improve dev_pm_opp_xlate_performance_state() to handle 1:1 pstate mapping between genpd and its master and also to fix a problem while finding the dst_table. - Handle pstate=0 case properly. -- viresh Ulf Hansson (1): PM / Domains: Make genpd performance states orthogonal to the idlestates Viresh Kumar (5): OPP: Improve _find_table_of_opp_np() OPP: Add dev_pm_opp_xlate_performance_state() helper PM / Domains: Save OPP table pointer in genpd PM / Domains: Factorize dev_pm_genpd_set_performance_state() PM / Domains: Propagate performance state updates drivers/base/power/domain.c | 207 ++++++++++++++++++++++++++---------- drivers/opp/core.c | 59 ++++++++++ drivers/opp/of.c | 14 ++- include/linux/pm_domain.h | 6 ++ include/linux/pm_opp.h | 7 ++ 5 files changed, 235 insertions(+), 58 deletions(-) -- 2.19.1.568.g152ad8e3369a
