[PATCH 03/13] OMAP2xxx clock: GFX functional clock rates are not independently changeable

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
