However there is no owner for them so if they listed as belonging to power domain we'll try toggling them up and down during power domain transition. As a result we either fail to suspend or resume the system. Changes in v11: - fix pm_genpd_init(&pd->genpd, NULL, false); Changes in v10: - this switches over domain infos to use masks instead of recomputing them each time and also gets rid of custom domain translator and uses standard onecell on. - fix missing the #include - remove the notes Changes in v9: - add document decription - fix v8 changes as follows: - This reconciles the v2 and v7 code so that we power domain have lists of clocks they toggle on and off during power transitions and independently from power domains clocks we attach clocks to devices comprising power domain and prepare them so they are turn on and off by runtime PM. - add rockchip_pm_add_one_domain() to control domains. - add pd_start/pd_stop interface to control clocks - add decription for power-doamin node Changes in v8: - document go back to v2 - This reconciles the v2 and v7 code so that we power domain have lists of clocks they toggle on and off during power transitions and independently from power domains clocks we attach clocks to devices comprising power domain and prepare them so they are turn on and off by runtime PM. - DTS go back to v2 Changes in v7: - Delete unused variables Changes in v6: - delete pmu_lock - modify dev_lock using mutex - pm_clk_resume(pd->dev) change to pm_clk_resume(ed->dev) - pm_clk_suspend(pd->dev) change to pm_clk_suspend(ed->dev) - add devm_kfree(pd->dev, de) in rockchip_pm_domain_detach_dev Changes in v5: - delete idle_lock - add timeout in rockchip_pmu_set_idle_request() Changes in v4: - use list storage dev Changes in v3: - DT structure has changed - change use pm_clk_resume() and pm_clk_suspend() - Decomposition power-controller, changed to multiple controller (gpu-power-controller, hevc-power-controller) Changes in v2: - move clocks to "optional" - remove the "pd->pd.of_node = np" - make pd_vio clocks all one entry per line and alphabetize. - power: power-controller move back to pinctrl: pinctrl.
