Subject: [PATCH 4/4] ARM: OMAP2+: Sync hwmod state with the pm_runtime and omap_device state
Date: Mon, 22 Jul 2013 15:31:17 +0530	[thread overview]
Message-ID: <1374487277-26099-5-git-send-email-rnayak@ti.com> (raw)
In-Reply-To: <1374487277-26099-1-git-send-email-rnayak@ti.com>

Some hwmods which are marked with HWMOD_INIT_NO_IDLE are left in enabled
state post setup(). When a omap_device gets created for such hwmods
make sure the omap_device and pm_runtime states are also in sync for such
hwmods by doing a omap_device_enable() and pm_runtime_set_active() for the
device.
