From f2e6142cdc10b1b7edea8d65b07293f152e4d110 Mon Sep 17 00:00:00 2001 From: Hien Dang Date: Tue, 13 Mar 2018 17:18:17 +0900 Subject: pwm: rcar: Use PM Runtime to control module clock Runtime PM API (pm_runtime_get_sync/pm_runtime_put) should be used to control module clock instead of clk_prepare_enable and clk_disable_unprepare.
