Is there a way to change the CLOCKACTIVITY field in certain cases? What I mean is: the 0x2 means that ICLK can be switched off, PRCM FCLK must kept on I have a setup, where I can switch off the FCLK for a period of time (so PER domain can hit retention). For this I'll need to have 0x0 in CLOCKACTIVITY. I'm not sure what are the side effects if we always use 0x0, but IMHO that shall be fine as well. -- Péter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
