OMAP: Introduce voltage domain information in the hwmod structures

thara-zz · metaliveblog · commit 3b92408c7dfe · 2010-12-22T14:31:32.000-08:00
This patch extends the device hwmod structure to contain
info about the voltage domain to which the device belongs to.
This is needed to support a device based DVFS where the
device knows which voltage domain it belongs to.
