Hi Viresh and Saravana,
Do you still have plans to push this? I've tested on mt8183 cci with:
1. [v4,0/5] Add required-opps support to devfreq passive gov (https://patchwork.kernel.org/project/linux-pm/cover/20190724014222.110767-1-saravanak@google.com/): patch 2, 4, 5
2. opp: Allow lazy-linking of required-opps (https://patchwork.kernel.org/project/linux-pm/patch/20190717222340.137578-4-saravanak@google.com/#23020727), with minor diff to let non genpd use required-opp as well: @@ -474,13 +474,6 @@ static void lazy_link_required_opp_table(struct opp_table *required_opp_table) struct device_node *required_np, *opp_np, *required_table_np; int i, ret;
- /* - * We only support genpd's OPPs in the "required-opps" for now, - * as we don't know much about other cases. - */ - if (!required_opp_table->is_genpd) - return; - mutex_lock(&opp_table_lock);
list_for_each_entry_safe(opp_table, temp, &pending_opp_tables, pending) {
3. PM / devfreq: Add cpu based scaling support to passive_governor and mt8183 cci, cpufreq series (https://patchwork.kernel.org/project/linux-mediatek/cover/1594348284-14199-1-git-send-email-andrew-sh.cheng@mediatek.com/)
Thanks
