Continuing the discussion here: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg43509.html 1. It appears that the OMAP4 powerdomain ON-ACTIVE state is a new state for OMAP4, and does not exist as such on previous chips (unless the PRM_VOLTCTRL.AUTO_* bits are all disabled) 2. It also appears that the OMAP4 powerdomain ON-INACTIVE state is equivalent to the OMAP3 powerdomain ON state (again, assuming that the PRM_VOLTCTRL.AUTO_SLEEP bit is set on OMAP3). Could you please comment on whether these statements are true or false? - Paul -- 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
