Subject: [PATCH/RFC 09/19] OMAP2: add voltage domains and connect to powerdomains
Date: Wed, 23 Mar 2011 17:00:23 -0700	[thread overview]
Message-ID: <1300924833-26745-10-git-send-email-khilman@ti.com> (raw)
In-Reply-To: <1300924833-26745-1-git-send-email-khilman@ti.com>

Create basic voltagedomains for OMAP2 and associate OMAP2 powerdomains
with the newly created voltage domains.
