From 1bb294a7981c737e2311a78e4086635ac0220ace Mon Sep 17 00:00:00 2001 From: Taniya Das Date: Mon, 20 Dec 2021 22:13:55 +0530 Subject: [PATCH] clk: Enable/Disable runtime PM for clk_summary The registers for some clocks in the SOC area, which are under the power domain are required to be enabled before accessing them. During the clk_summary if the power-domains are not enabled they could result into NoC errors. Thus ensure the register access of the clock controller is done with pm_untime_get/put functions.
