Subject: [PATCH 03/13] OMAP2xxx clock: GFX functional clock rates are not independently changeable
Date: Thu, 11 Feb 2010 11:16:32 -0700	[thread overview]
Message-ID: <20100211181628.795.33736.stgit@localhost.localdomain> (raw)
In-Reply-To: <20100211181236.795.56094.stgit@localhost.localdomain>

According to the OMAP242x TRM Rev X Figure 5-15 "Clock Output Control
- Functional Clocks 2", the GFX functional clocks should be marked
both DELAYED_APP and CONFIG_PARTICIPANT, meaning that their rates must
be reprogrammed as part of a larger OPP set change.
