From 98d277a79126a2df8a2617215846d01f823cfffa Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Wed, 2 Oct 2024 14:22:25 +0200 Subject: PM: domains: Support required OPPs in dev_pm_domain_attach_list() In the multiple PM domain case we need platform code to specify the index of the corresponding required OPP in DT for a device, which is what *_opp_attach_genpd() is there to help us with. However, attaching a device to its PM domains is in general better done with dev_pm_domain_attach_list(). To avoid having two different ways to manage this and to prepare for the removal of *_opp_attach_genpd(), let's extend dev_pm_domain_attach|detach_list() to manage the required OPPs too.
