From 2f71ae1a9e75a675dfc9da03f5e191e858d1126f Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Mon, 4 Jul 2022 21:07:28 +0530 Subject: [PATCH] OPP: Allow config_clks helper for single clk case There is a corner case with Tegra30, where we want to skip clk configuration via dev_pm_opp_set_opp(), but still want the OPP core to read the "opp-hz" property so we can find the right OPP via freq finding helpers. This is the easiest of the ways to make it work, without any special hacks in the OPP core. Allow config_clks to be passed for single clk case.
