But be sure to guarantee regulator enable/disable balancing. Seems like the problem was with calling musb_platform_resume to in omap2430.c init. This caused the regulators to be enabled unnecessarily. Replaced that in our .37 kernel with similar things that there currently is in upstream with omap2430_low_level_init(musb). Thanks for the help. I'm next going to start digging deeper to the ISP1707 power leaks. - Kalle > > -- > balbi > -- > To unsubscribe from this list: send the line "unsubscribe linux-usb" in the > body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at > http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
