Subject: [PATCH 01/12] OMAP2/3 clockdomains: add CM and PRM clkdms
Date: Mon, 08 Sep 2008 10:57:39 -0600 [thread overview]
Message-ID: <20080908165736.2540.45514.stgit@localhost.localdomain> (raw)
In-Reply-To: <20080908164444.2540.98619.stgit@localhost.localdomain>
Add clockdomains for the CM and PRM. These will ultimately replace the
"wkup_clkdm", which appears to not actually exist on the hardware.
