From 20729300cabdad60333e52278bd2dd25e5d85518 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Fri, 22 Apr 2016 14:57:29 +0200 Subject: [PATCH] clk: renesas: mstp: Use always-on governor for Clock Domain As a pure Clock Domain does not have the concept of powering the domain itself, the CPG/MSTP driver does not provide power_off() and power_on() callbacks. However, the genpd core may still perform a dummy power down, causing /sys/kernel/debug/pm_genpd/pm_genpd_summary to report the domain's status being "off-0". Use the always-on governor to make sure the domain is never powered down, and always shows up as "on" in pm_genpd_summary.
