v5 cover PM / Domains: Add support for 'required-opps' to set default perf state

v5: Dropped all default_pstate handling in runtime suspend/resume

v4: Fixed error handling in __genpd_dev_pm_attach()

This is a re-spin of the series [1] which was adding support for a new DT binding (assigned-performance-state) and based on the discussions on that thread [2] it was concluded that we could achieve the same with the existing 'required-opps' binding instead.

So this series, just drops the new binding and uses required-opps to achieve the default perf state setting thats needed by some devices.

---
Some devics within power-domains with performance states do not support DVFS, but still need to vote on a default/static state while they are active. Add support for this using the 'required-opps' property in device tree.

PATCH v5 1/2 PM / Domains: Add support for 'required-opps' to set default perf state

Some devices within power domains with performance states do not support DVFS, but still need to vote on a default/static state while they are active. They can express this using the 'required-opps' property in device tree, which points to the phandle of the OPP supported by the corresponding power-domains.

Add support to parse this information from DT and then set the specified performance state during attach and drop it on detach. runtime suspend/resume callbacks already have logic to drop/set the vote as needed and should take care of dropping the default perf state vote on runtime suspend and restore it back on runtime resume.

This doesn't look entirely correct to me. If we fail to translate a required opp to a performance state, we shouldn't try to set it.

Perhaps it's also easier to call of_get_required_opp_performance_state() unconditionally of whether a "required-opps" specifier exists. If it fails with the translation, then we just skip setting a default state and continue with returning 1.

Would that work?

I think it should, I'll redo the error handling, hopefully right this time, and re-post. Thanks for the review.

Looks like calling of_get_required_opp_performance_state() unconditionally makes it spit out a pr_err() in case the node is missing "required-opps" property, so I posted a v6 [1] with the check in place and adding the missing else condition.

Please use dev->of_node instead (it is set to the same of_node as base_dev by the callers of __genpd_dev_pm_attach) as it's more consistent with existing code.

This doesn't look entirely correct to me. If we fail to translate a required opp to a performance state, we shouldn't try to set it.

yeah, that does not seem right at all :(

Perhaps it's also easier to call of_get_required_opp_performance_state() unconditionally of whether a "required-opps" specifier exists. If it fails with the translation, then we just skip setting a default state and continue with returning 1.

Would that work?

Looks like calling of_get_required_opp_performance_state() unconditionally makes it spit out a pr_err() in case the node is missing "required-opps" property, so I posted a v6 [1] with the check in place and adding the missing else condition.

I see.

Viresh, would it make sense to remove that print? I mean, the required-opps property could be considered as optional and it seems a bit silly that a pre-parsing of the property is needed to figure that out.

PATCH v5 2/2 arm64: dts: sc7180: Add required-opps for i2c

In reply to Rajendra Nayak

qup-i2c devices on sc7180 are clocked with a fixed clock (19.2 MHz) Though qup-i2c does not support DVFS, it still needs to vote for a performance state on 'CX' to satisfy the 19.2 Mhz clock frequency requirement.

Use 'required-opps' to pass this information from device tree, and also add the power-domains property to specify the CX power-domain.
