From 8b3bd6ffbc6475a7dc92c6d6021d49b555301c01 Mon Sep 17 00:00:00 2001 From: Manivannan Sadhasivam Date: Tue, 3 Oct 2023 16:42:28 +0530 Subject: PM / devfreq: Switch to dev_pm_opp_find_freq_{ceil/floor}_indexed() APIs Some devfreq consumers like UFS driver need to work with multiple clocks through the OPP framework. For this reason, OPP framework exposes the _indexed() APIs for finding the floor/ceil of the supplied frequency of the indexed clock. So let's use them in the devfreq driver. Currently, the clock index of 0 is used which works fine for multiple as well as single clock.
