Yes. It is duplicate for OMAP2 and OMAP3 devices as well.
Actually this should have been fixed when the driver was
hwmod converted but some how got missed. We noticed
an issue on OMAP5, when timer interrupts stopped firing when
always on clock domain was allowed to idle. This was because
this reset was clearing the correctly set sysc value by hwmod.

The patch is also tested on ZOOM3 ( OMAP3630)
and OMAP2430SDP.
