From 2ee619f9487c2acc1efdf2c78e68e2bd51b635fa Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 13 Mar 2012 22:40:00 +0100 Subject: PM / shmobile: Make TMU driver use pm_genpd_dev_always_on() Make the TMU clocksource driver mark its device as "always on" using pm_genpd_dev_always_on() to protect it from surprise power removals and make sh7372_add_standard_devices() add TMU devices on sh7372 to the A4R power domain so that their "always on" flags are taken into account as appropriate.
